7 Continents And 5 Oceans

The 7 continents of the world are North America, South America, Antarctica, Europe, Asia, Africa, and Australia. The 5 oceans of the world are the Atlantic Ocean, the Indian Ocean, the Pacific Ocean, the Southern Ocean, and the Arctic Ocean.

One of the most fascinating scientific topics is the study of the 5 oceans and 7 continents. The reason for this is that, even though most of us study the world’s oceans and continents at school, very often we found ourselves in conversations where people do not seem to agree on the exact number of continents and oceans.

When we contemplate the whole globe as one great dewdrop, striped and dotted with continents and islands, flying through space with other stars all singing and shining together as one, the whole universe appears as an infinite storm of beauty. – John Muir

Can you name the 7 continents of the world?

  • North America
  • South America
  • Antarctica
  • Europe
  • Asia
  • Africa
  • Australia

And even when we know that the correct number is 7 continents and 5 oceans, it is more challenging than it may initially seem to name them all.

Why does studying continents and oceans so important? Because if you want to understand Planet Earth, you really need to understand the planet’s surface. Most of the surface is actually covered in water (about 70%). More than 95% of it is saltwater. This saltwater surface has been organized into 5 distinct oceans, whereas the relatively small land surface we have organized into 7 distinct continents.

Four Continents Five Continents Six Continents Six Continents (Alt.) Seven Continents
Afro-Eurasia Africa Africa Africa Africa
America Eurasia Asia Eurasia Asia
Antarctica America Europe North America Europe
Australia Antarctica America South America North America
Australia Antarctica Antarctica/Oceania South America
Australia Australia Antarctica/Oceania
Australia

What are continents? 

At its most basic, we could say that continents are the areas of our planet’s surface that are not underwater.

Anyone with a sharp mind would immediately pick holes in that definition. Why? Because the shapes and boundaries of continents are always changing. As oceans rise, continents become, by that definition, smaller.

But not only that, the land masses that we now call continents are the result of shifts that broke up a supercontinent that scientists have called Pangea. It would be a mistake to think that the shifts that created the 7 continents have stopped. These shifts continue and will create new continents in the distant future (we are talking about hundreds of millions of years from now).

How many continents are there?

Although the number seven is the most common for continents, there are two other widely spread and fairly accepted number of continents.

It used to be believed that there were only 5 continents. Indeed, some people still believe to be the case. The five continents would be the following:

  • Africa
  • America
  • Asia
  • Australia
  • Europe

Other people believe that there are 6 continents, as follows:

  • America
  • Antarctica
  • Asia
  • Africa
  • Australia (Oceania)
  • Europe

But, by far, the most commonly agreed number of continents is 7:

  • North America
  • South America
  • Africa
  • Antarctica
  • Australia (Oceania)
  • Europe
  • Asia

Whether you believe there are 5, 6, or 7 continents would largely depend on when and where (i.e., which country) you went to school. Some people would also take the landmass that encompasses Europe and Asia as one whole known as Eurasia. There is also a common misconception concerning Australia (the continent) and Australia (the country). The continent known indistinctly as Australia or Oceania should not be confused with the country of Australia, for Australia (the continent) includes Australia, Tasmania, New Guinea, and New Zealand, as well as Polynesian and Micronesian islands.

Africa 

This continent has a landmass of 11,670,0000 square miles or 28,489,869 square kilometers.

Africa is the second continent on the planet both in terms of size and population (1,119,307,147 as of 2016).

It is estimated that about 15% of the world’s population currently lives in Africa.

With the equator traversing the African continent roughly through its middle, Africa has distinct climatic regions. The areas immediately north and south of the equator have climates that vary from warm to tropical or a combination of both. The far north and the far south are, in contrast to the central areas, relatively temperate.

Because of this climatic diversity, Africa is home to many different animal and insect species that are unique to the continent. Elephants, hippos, and giraffes are just some of the animals that have made Africa globally famous.

From a historical perspective, Africa is hugely important as it is now credited to be the birthplace of humankind.

Present-day Africa is made up of 54 independent countries, most of which are the result of continent-wide independence and decolonization movements in the 20th century. Some of the arbitrary borders that were drawn by the former colonial overseers have resulted in bloody conflicts in many different parts of the continent.

  • Africa is surrounded by the Mediterranean Sea to the north, the Red Sea to the northeast, the Atlantic Ocean to the west, and the Indian Ocean to the east.
  • The largest city in the whole continent is Lagos, Nigeria inhabited by 15,188,780 people as of 2014.
  • Other large cities in Africa include Cairo, Egypt; Kinshasa, Democratic Republic of Congo; Johannesburg, South Africa; Khartoum, Sudan; Dar Es Salaam, Tanzania; and Alexandria, Egypt.

Antarctica

This continent has a land mass of 5,405,000 square miles or 12,949,940 square kilometers.

Antarctica is, by far, the most sparsely populated continent on Earth, with a population of only 4,912 people as of 2015.

Antarctica is mostly known for being the southernmost continent on our planet. Because of its geographical position in the South Pole, Antarctica suffers the coldest temperatures on Earth, sometimes reaching -130°F (-90°C).

With those harsh weather conditions, it is hardly surprising that this continent is so sparsely populated. Its largest “city” is the McMurdo Station where, as of 2013, only 1,258 people live.

Antarctica is one of the smallest continents on Earth, only larger than Europe and Australia. But, even though Antarctica is larger than Europe, its population is a lot smaller in size. In fact, Antarctica has the smallest population of all 7 continents.

Asia

With a land area of 17,210,000 square miles or 44,029,797 square kilometers, Asia occupies about 9% of our planet’s surface.

Asia is also the most widely populated continent on Earth with a population of 4,494,302,221 as of 2016. This means that almost 60% of the world’s population lives in Asia.

Because of the sheer size of its population and the rising economies of many of its countries (India, China, South Korea, Japan, etc.), Asia is one of the most important countries in terms of the world’s economy.

  • The largest city in Asia is also the largest city on Earth. The city in question is Tokyo, Japan with 37,126,000 as of 2012.
  • Other large cities in Asia include Jakarta, Indonesia; Delhi, India; Karachi, Pakistan; Seoul, South Korea; Shanghai, China; Manila, Philipines; and Mumbai, India.
  • Although a continuing landmass with Europe, Asia is the part of the landmass east of an imaginary line going north from the Aegean Sea all the way to the Black Sea, then on to the North West of the Caspian Sea, the Ural River and finally ending at the Arctic Ocean.
  • The Pacific Ocean is to the east of Asia, the Indian Ocean to the south and the Arctic Ocean to the north.

Australia 

This continent has a land area of 2,970,000 square miles or 5,179,976 square kilometers. As of 2016, its population is 39,901,000, making it the second least populated continent on Earth, only behind Antarctica.

  • In Australia, the largest city is Sydney which, as of 2016, has a population of 5,029,768.
  • Other large cities in Australia include Melbourne, Victoria; Brisbane, Queensland; Auckland, New Zealand; and Perth, Western Australia.
  • Australia is also known for being the remotest continent on the planet as it is the farthest from any of the other 6 continents. Australia is also the smallest continent although, paradoxically harbors one of largest countries on earth (Australia) in terms of size if not population.
  • When talking about this continent, we must always combat the common misconception that conflates the Commonwealth nation of Australia and, specifically, its mainland, with the whole continent, which also includes New Zealand (with its two large islands), Tasmania, and several other smaller islands.
  • Australia (also sometimes known as Oceania) is located between the Indian Ocean to the East and the Pacific Ocean to the West.

This continent has long fascinated botanists and biologists due to the uniqueness of the hundreds of different plant and animal species that are unique to this continent. The fact that the overwhelming percentage of animal and plant specifies present in Australia cannot be found anything else in the world is due to Australia’s remoteness.

Apart from its many different animal and plant species, this continent is also globally famous because it is home to the biggest reef in the world: The Great Barrier Reef.

Europe

  • With a land area of 3,931,000 square miles or 7,769,964 square kilometers, Europe is the smallest continent on Earth.
  • It is the westernmost area of the Eurasian landmass, which only makes up about 7% of the world’s land area.
  • The largest city in Europe is Istanbul, Turkey with a population of 14,657,434. Interestingly, the largest European city is also partially in Asia. Turkey is one of those nations that straddle two different continents (Russia is another important example). But its main city and Europe’s largest city also straddles both continents.
  • Other large cities in Europe include Moscow, Russia; London, United Kingdom; Saint Petersburg, Russia; Berlin, Germany; Madrid, Spain; Kieve, Ukraine; Rome, Italy; and Paris, France.
  • Europe is the most densely populated continent on Earth with a populated mainland stretching east from the Atlantic Ocean to the Ural Mountains. The continent is bordered by the Mediterranean and Black seas to the south, and the Antarctic Ocean to the north. Sicily, Corsica, Sardinia, The British Isles, or the Balearic Islands are also densely populated islands that are part of Europe.
  • Europe harbors both the largest and the smallest nations on Earth. The largest one is Russia (although most of its territory is, in fact, in Asia), and the smallest one is Vatican City in the Italic Peninsula.

Many different European civilizations have shaped the world because of their historical impact not just in Europe itself but also in every other continent on earth due to imperialistic expansion and its subsequent colonialism. Testament to this is that European languages (chiefly, English, Spanish, Portuguese, French, and Russian) are widely spoken in every other continent, mostly in North and South America (Spanish, English, French), Africa (English, French, Portuguese, Spanish), Asia (Russian, English, French, Portuguese), and Australia (English).

North America

  • This continent has a land area of 9,540,000 square miles or 23,309,892 square kilometers. As of 2016, its population is 579,014,000. This population is spread over 23 different countries including three that occupy vast lands, such as Canada, The United States, and Mexico.
  • This means that around 8% of the world’s population lives in this landmass, which is approximately 17% of the planet’s landmass.
  • Although ethnically diverse, its population is mostly of European descent, most of which live in the United States of America, Mexico, and Canada but also in the Caribbean islands and the nations of Central America.
  • The largest city in North America is Mexico City with a population of 20,400,000. This also makes it the third-largest city in the world behind Tokyo, Japan and São Paulo, Brazil.
  • Other largest cities in North America include New York City, New York; Los Angeles, California; Chicago, Illinois; Boston, Massachusetts; Toronto, Ontario; Dallas-Fort Worth, Texas; Miami, Florida; Philadelphia, Pennsylvania.
  • North America presents a great variety of climate, from the extreme cold in Alaska, Canada, and most of the northern section of the United States, to tropical and subtropical on the East coast, or desert conditions in the southwest of the United States, and the northwest of Mexico.
  • North America is also home to the world’s largest lakes, straddling Canada and United States.

Mostly due to the global economic powerhouses that are Canada and, mostly, the United States, North America is the richest continent in the world. This is in terms of  Gross domestic product (GDP) per capita, which is the largest of all the continents.

South America

  • This continent has a land area of 6,888,000 square miles or 15,539,928 square kilometers. Its population is 414,332,000 as of 2015.
  • The biggest city in South America is São Paulo in Brazil with a population of 21,242,939. This makes São Paulo the second largest global city, only behind Tokyo in Japan.
  • Other largest cities in South America include Lima, Peru; Bogotá, Colombia; Rio de Janeiro, Brazil; Santiago, Chile; Caracas, Venezuela; Buenos Aires, Argentina; Salvador, Brazil; Brasilia, Brazil; Fortaleza, Brazil; Guayaquil, Ecuador; and Quito, Ecuador.
  • This continent is the southern area of the landmass it shares with North America. Like North America, South America borders with the Atlantic Ocean to the West and the Pacific to the East. South America stretches all the way to the South Pole where its nearest neighboring continent, Antarctica, is located.
  • Despite its vastness, there are only twelve independent nations in South America. By far, the largest of them all is Brazil. Not only is Brazil the biggest country on the continent, but it also has the largest population of them all.
  • Because of the Amazon River, which is the longest river in the world, only followed by the Nile in Africa; and the Andes mountains, which is the longest mountain range in the world, South America has a fascinating level of biodiversity.
  • The ethnic diversity of South America is the result of southern migration of indigenous North American populations, followed by the arrival of Europeans who initially where the conquistadors, explorers, and colonists from Spain and Portugal and then immigrants from those countries and other European nations, and, chiefly, in Brazil the import of slaves from South Saharan Africa.

Although for hundreds of years, the global consensus was that there were 4 oceans, in the 21st century this number was officially increased to 5 when in the year 2000 the International Hydrographic Organization decided almost unanimously to include the Southern Ocean.

So, the list of the 5 oceans is now as follows:

  • The Pacific Ocean
  • The Atlantic Ocean
  • The Indian Ocean
  • The Arctic Ocean
  • The Southern Ocean

Pacific Ocean

“The history of exploration has never been driven by exploration. But Columbus himself was a discoverer. So was Magellan. But the people who wrote checks were not. They had other motivations.” – Neil deGrasse Tyson

  • This ocean covers an area of 63,784,077 square miles or 165,200,000 square kilometers.
  • The Pacific ocean covers the whole area between the eastern coasts of two continents: Australia (Oceania) and Asia, all the way to the west coasts of North and South America.
  • The Pacific ocean was discovered by Europeans in 1520 when Portuguese explorer Magellan accessed it from South America for the first time.
  • Two notable facts make this ocean world famous. On the one hand, the Pacific has the longest shoreline in the world. Taking into account all the different shorelines washed by the Pacific and add them together, the Pacific has 84,3000 miles or 135,663 kilometers of shoreline.
  • The other notable fact about the Pacific is that its seafloor holds the deepest point on the whole planet. Back in 1875, the HMS Challenger discovered it around the US territory of Guam, specifically in the Marianas Trench. The depth of the seafloor is close to 7 miles or 11,000 meters below sea level.

Atlantic Ocean

  • With an area of 41,081,270 square miles or 106,400,000 square kilometers, the Atlantic is the second-largest ocean on Earth behind the Pacific.
  • Like the Pacific ocean, the Atlantic stretches all the way from the Arctic to the Antarctic region. It covers the area between western Europe and Africa to western North and South America.
  • The Atlantic includes many seas, such as the Baltic, the Caribbean, the Gulf of Mexico, and the Mediterranean seas.
  • Europeans were able to chart this ocean fully in the 15th century when they began sailing to North and South America. This makes it, together with the eastern portion of the Indian Ocean, the oldest ocean to be chartered by Europeans.
  • Since then, the Atlantic has become hugely important in world trade. The Atlantic ocean has played a key role in the imperialistic and colonialist enterprises by European states (Spain, Portugal, Great Britain, France, etc.).
  • The fertility of the warm waters of the North Atlantic specifically has also contributed to human development thanks to the abundance of whale sperm and cod.

Indian Ocean

  • Comprising the area between East Africa, South East Asia and the east of Australia, the Indian Ocean covers an area of 28,400,130 square miles or 73,556,000 square kilometers.
  • Washing the shores of some of the world’s most important civilizations, the Indian Ocean has been crucial in trade for several hundreds of years.
  • Historically, the Indian Ocean has been fundamental in the trade between Europe and Asia. Western (and, indeed, global) medicine and food preservation have greatly progressed thanks to the amazing spices that are found in the countries around the Indian Ocean, including its many islands.
  • Europeans recognized the importance of these species centuries ago, so the sailed throughout the Indian Ocean in search of them.

Arctic Ocean

  • Both the smallest and the shallowest ocean, the Arctic Ocean covers an area of 5,400,015 square miles or 13,986,000 square kilometers.
  • The Arctic Ocean is surrounded by North America, Asia, and Europe.
  • This ocean, which is mostly covered in ice for most of the year, includes the Barents, North and Hudson Bay seas.
  • Despite the freezing temperatures and the fact that most of the area covered in ice, different Northern civilizations from the three continents that surround it have inhabited for hundreds of years.
  • Perhaps this was what encouraged Europeans explorers to attempt to use the Arctic Ocean to access Asia. This was supposed to be a shorter pass that the already exploited one of the Indian Ocean. However, because of its incredibly harsh climatic conditions, this exploring enterprise was an utter failure.

Southern Ocean

  • The area covered by the Southern Ocean is 7,848,299 square miles or 20,327,000 square kilometers. This makes it the penultimate ocean in terms of size only in front of the Arctic Ocean.
  • The Southern Ocean is the “youngest” ocean on Earth, as it was only considered as such in the year 2000. Before then it was merely considered a southern extension of the Atlantic, the Pacific, and the Indian Oceans. This is because its waters are joined to the north with the southern portions of the Indian, the Atlantic, and the Pacific Oceans.
  • The Southern Ocean is hugely important in global weather patterns, and not just those affecting the southern hemisphere.

So, how many continents and oceans are there, really?

When it comes to the study of the continents and oceans on planet Earth, we need to recognize that the number of continents and oceans (and sometimes the terminology we use) has changed and new perspectives are put forward and new consensuses are reached by the scientific community. And, although, we must always acknowledge any possible discrepancies we have to always work on the basis of the current scientific consensus. And right now, in 2017, the scientific consensus is that there are 7 continents and 5 oceans.

Continents and Oceans

Continents and Oceans: There are 7 continents and 5 oceans in the world. To understand the planet Earth it is important to learn about the 7 Continents and 5 Oceans. Out of the total earth’s surface, 21% is under the Continent and 72% is under Ocean. In terms of land area, Asia is the largest continent among all and the Oceanic is the smallest. The Pacific Ocean is the largest ocean in the world. It is nearly two times larger than the second-largest ocean.

In this article, we are providing detailed information about the continents and oceans. It is a very interesting topic as it develops the knowledge about the geography of planet earth. Here is the detailed information for the Continents and Ocean.

What is a Continent?

A continent is any of several large landmasses which are separated by an ocean or other landmass. Continents are divided into 7 different regions namely, Asia, North America, Antarctica, South America, Europe, Africa, and Australia. Many of the island countries are surrounded by the Pacific Ocean which together forms the continent of Australia, and that region is geographically called Oceania. According to geology, a continent can be defined as “Earth’s major landmass that includes dry mass and the Continental shelves both.

What is Ocean?

An Ocean is referred to as a salty water body that covers 71% of the Earth’s surface. In other words, it can be defined as a very large body of water due to which the greater ocean has been divided. There are five different oceans: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Arctic Ocean, and the Southern Ocean. The Pacific Ocean is the largest Ocean in the world. The Pacific Ocean also contains the Mariana Trench, which is the deepest known part of the world’s oceans. Its deepest point reaches seven miles down into the Earth

    • The ocean is the largest object of the hydrosphere and is part of the World Ocean, which covers about 71% of the surface of our planet. The oceans wash the shores of the continents, have a system of water circulation and have other specific features. The oceans of the world are in constant interaction with all the shells of the Earth.

    Map of the oceans and continents of the world

    Some sources indicate that the World Ocean is divided into 4 oceans, but in 2000, the International Hydrographic Organization identified the fifth — the Southern Ocean. This article provides a list of all 5 oceans of planet Earth in order — from the largest in area to the smallest, with the name, location on the map and main characteristics.

    Pacific Ocean

    See also: Which continents and countries is washed by the Pacific Ocean?

    The Pacific Ocean is one of the five oceans in the world. This is the largest ocean on our planet, with an area of ​​165.25 million km². It stretches from the Arctic Ocean in the north to the Southern Ocean in the south, and borders parts of the world such as Asia, Australia, North America and South America, as well as a number of Pacific islands.

    Due to its large size, the Pacific Ocean has a unique and varied topography. It also plays an important role in shaping the world’s weather patterns and the modern economy.

    The ocean floor is constantly changing through the movement and subduction of tectonic plates. Currently, the oldest known area of ​​the Pacific Ocean is about 180 million years old.

    Geologically, the region surrounding the Pacific Ocean is sometimes referred to as the Pacific Ring of Fire. The region has this name because it is the world’s largest area of ​​volcanism and earthquakes. The Pacific region is subject to violent geological activity, because much of its floor is in subduction zones, where the boundaries of some tectonic plates are pushed under others after a collision. There are also some hotspot areas where magma from the Earth’s mantle is forced out through the Earth’s crust, creating underwater volcanoes that can eventually form islands and seamounts.

    The Pacific Ocean has a diverse bottom topography, consisting of oceanic ridges and deep sea trenches that have formed in hot spots below the surface. The relief of the ocean differs significantly from large continents and islands. The deepest point of the Pacific Ocean is called the «Challenger Abyss», it is located in the Mariana Trench, at a depth of almost 11 thousand meters. The largest island in the Pacific Ocean is New Guinea.

    The climate of the ocean varies greatly depending on the latitude, the presence of land and the types of air masses moving over its waters. Ocean surface temperature also plays a role in climate as it affects the availability of moisture in different regions. Around the equator, the climate is tropical, humid and warm for most of the year. The far north Pacific and the far south are more temperate, with large seasonal differences in weather patterns. In addition, some regions are dominated by seasonal trade winds that affect the climate. Tropical cyclones and typhoons also form in the Pacific Ocean.

    The marine ecosystems of the Pacific Ocean are essentially the same as those of other oceans on Earth, except for local temperatures and water salinity. The pelagic zone of the ocean is home to marine animals such as fish, marine mammals, and plankton. Invertebrates and scavengers live at the bottom. Coral reef habitats can be found in sunny, shallow ocean areas close to the coast. The Pacific Ocean is the environment that is home to the greatest variety of living organisms on the planet.

    Atlantic Ocean

    See also: Which continents and countries are washed by the Atlantic Ocean?

    The Atlantic Ocean is the second largest ocean on Earth with a total area (including adjacent seas) of 106.46 million km². It occupies about 22% of the planet’s surface area. The ocean has an elongated S-shape and stretches between North and South America in the west, and Europe and Africa in the east. It connects to the Arctic Ocean to the north, the Pacific Ocean to the southwest, the Indian Ocean to the southeast, and the Southern Ocean to the south. The average depth of the Atlantic Ocean is 3,736 m, and the deepest point is located in the Puerto Rico Ocean Trench, at a depth of 8,742 m. The Atlantic Ocean has the highest salinity of any ocean in the world.

    Its climate is characterized by warm or cool water, which circulates in different currents. Water depth and winds also have a significant effect on ocean surface weather. Severe Atlantic hurricanes are known to develop off the coast of Cape Verde in Africa, heading towards the Caribbean from August to November.

    The time when the supercontinent Pangea broke up, about 130 million years ago, was the beginning of the formation of the Atlantic Ocean. Geologists have determined that it is the second youngest of the world’s five oceans. This ocean has played a very important role in connecting the Old World with the newly explored America since the late 15th century.

    The main feature of the floor of the Atlantic Ocean is an underwater mountain range called the Mid-Atlantic Ridge, which extends from Iceland in the north to approximately 58°S. sh. and has a maximum width of about 1600 km. The water depth above the ridge is less than 2,700 meters in most places, and several mountain peaks of the ridge rise above the water to form islands.

    The Atlantic Ocean flows into the Pacific Ocean, however their habitats are not always the same due to water temperature, ocean currents, sunlight, nutrients, salinity, etc. The Atlantic Ocean has coastal and open ocean habitats. Its coastal ecosystems are located along coastlines and extend to the continental shelves. Marine life is usually concentrated in the upper layers of the ocean waters, and closer to the shores are coral reefs, mangroves, kelp forests and sea grasses.

    The Atlantic Ocean is of great modern importance. The construction of the Panama Canal, located in Central America, allowed large ships to pass through the waterways, from Asia across the Pacific Ocean to the east coast of North and South America across the Atlantic Ocean. This led to a revival of trade between Europe, Asia, South America and North America. In addition, there are deposits of gas, oil and precious stones at the bottom of the Atlantic Ocean.

    Indian Ocean

    See also: Which continents and countries are washed by the Indian Ocean?

    The Indian Ocean is the third largest ocean on the planet and has an area of ​​70.56 million km². It is located between Africa, Asia, Australia and the Southern Ocean. The Indian Ocean has an average depth of 3,963 m, and the Sunda Trench is the deepest trench, with a maximum depth of 7,258 m. The Indian Ocean occupies about 20% of the area of ​​the World Ocean.

    The formation of this ocean is a consequence of the breakup of the Gondwana supercontinent, which began about 180 million years ago. 36 million years ago, the Indian Ocean assumed its current configuration. Although it first opened about 140 million years ago, almost all Indian Ocean basins are less than 80 million years old.

    It is landlocked in the Northern Hemisphere and does not extend into Arctic waters. It has fewer islands and narrower continental shelves compared to the Pacific and Atlantic Oceans. Below the surface layers, especially in the north, the ocean water is extremely low in oxygen.

    The climate of the Indian Ocean varies greatly from north to south. For example, monsoons dominate in the northern part, above the equator. From October to April, strong northeasterly winds are observed, while from May to October — southerly and western ones. The Indian Ocean also has the warmest weather of all five oceans in the world.

    The deep ocean contains about 40% of the world’s marine oil reserves, and seven countries currently extract minerals from this ocean.

    The Seychelles is an archipelago in the Indian Ocean, consisting of 115 islands, and most of them are granitic islands and coral islands. On granitic islands, most of the species are endemic, and coral islands have a coral reef ecosystem, where the biodiversity of marine life is greatest. The Indian Ocean has an island fauna that includes sea turtles, seabirds and many other exotic animals. Much of the marine life in the Indian Ocean is endemic.

    The entire marine ecosystem of the Indian Ocean is facing species decline as water temperatures continue to rise, which in turn results in a 20% decline in phytoplankton, on which the marine food chain is highly dependent.

    Southern Ocean

    Southern Ocean on the map of the Earth / Wikipedia

    In 2000, the International Hydrographic Organization identified the fifth, youngest ocean in the world — the Southern Ocean — from the southern regions of the Atlantic, Indian and Pacific oceans. The New Southern Ocean completely surrounds Antarctica and extends from its coast north to 60°S. sh. The Southern Ocean is by far the fourth largest of the world’s five oceans, only larger than the Arctic Ocean.

    In recent years, a lot of oceanographic research has focused on ocean currents, first because of El Niño and then because of the wider interest in global warming. One study determined that currents near Antarctica would isolate the Southern Ocean as a separate ecosystem, so it was identified as a separate, fifth ocean.

    The area of ​​the Southern Ocean is approximately 20.3 million km². The deepest point is 7,235 meters deep and is located in the South Sandwich Trench.

    The water temperature in the Southern Ocean varies from -2° C to +10° C. It also contains the largest and most powerful cold surface current on Earth, the Antarctic Circumpolar Current, which moves eastward and is 100 times the flow of all the world’s rivers .

    Despite the identification of this new ocean, it is likely that the debate about the number of oceans will continue into the future. After all, there is only one «World Ocean» since all 5 (or 4) oceans on our planet are interconnected with each other.

    Arctic Ocean

    Arctic Ocean on the Earth map/Wikipedia

    See also: Which continents and countries are washed by the Arctic Ocean?

    The Arctic Ocean is the smallest of the world’s five oceans and has an area of ​​14. 06 million km². Its average depth is 1205 m, and the deepest point is in the underwater Nansen Basin, at a depth of 4665 m. The Arctic Ocean is located between Europe, Asia and North America. In addition, most of its waters are north of the Arctic Circle. The geographic North Pole is located in the center of the Arctic Ocean.

    While the South Pole is located on a continent, the North Pole is covered by water. For most of the year, the Arctic Ocean is almost completely covered by drifting polar ice, which is about three meters thick. This glacier usually melts during the summer months, but only partially.

    Because of its small size, many oceanographers do not consider it an ocean. Instead, some scientists suggest that it is a sea that is mostly enclosed by continents. Others believe that this is a partially closed coastal body of the Atlantic Ocean. These theories are not widely held, and the International Hydrographic Organization considers the Arctic Ocean one of the world’s five oceans.

    The Arctic Ocean has the lowest water salinity of any of the Earth’s oceans because of the low evaporation rate and the fresh water coming from the streams and rivers that feed the ocean, diluting the salt concentration in the water.

    The polar climate dominates this ocean. Consequently, winters exhibit relatively stable weather with low temperatures. The best known characteristics of this climate are polar nights and polar days.

    It is believed that the Arctic Ocean may contain about 25% of the total natural gas and oil reserves on our planet. Geologists have also established that there are significant deposits of gold and other minerals. The abundance of several species of whales, fish and seals also make the region attractive to the fishing industry.

    There are several animal habitats in the Arctic Ocean, including endangered mammals and fish. The region’s vulnerable ecosystem is one of the factors that make the fauna so sensitive to climate change. Some of these species are endemic and irreplaceable.
