What are the 4 oceans
What are the four major ocean basins from largest to smallest?
Aug 05, · The four oceans are the Pacific, Atlantic, Indian and Arctic, and the seven continents are North America, South America, Africa, Asia, Antarctica, Europe and Australia. However, some geographers consider there to be five oceans and either five or six continents. Earth Details The surface of the planet is approximately 71% water and contains (5) five oceans, including the Arctic, Atlantic, Indian, Pacific and Southern. Their borders are indicated on the world image (above) in varied shades of lovetiktokhere.com: John Moen.
The oceans of the Earth are all hwat. They are truly one "world ocean" which covers about 71 percent of the Earth's surface. The salt water which aare from one part of the ocean to another without hindrance makes up 97 percent of the planet's water supply. Geographers, whay many years, divided the world ocean into four parts: the Atlantic, Pacific, Indian, and Arctic Oceans.
Odeans addition to these oceans, they also described many other ooceans bodies of salt water including seas, bays, and estuaries. It wasn't until that a fifth ocean was officially named: the Southern Ocens, which includes the waters around Antarctica.
The Pacific Ocean is by far the world's largest ocean at 60, square miles , sq km. According to the CIA World Factbook, it covers 28 percent of the Earth and is equal in size to nearly ade of the land area on the Earth. It has an average depth of 13, feet 4, metersbut its deepest point is the Challenger Hwat within the Mariana Trench near Japan. This area is also the deepest point in the world atfeetmeters.
How to skin a djembe Pacific Ocean is important to geography not only because of its size but also because it has been a major historical route of exploration and migration.
The Atlantic Ocean is the world's second-largest ocean with an area of 29, square miles 76, sq. The average depth of the Atlantic Ocean is 12, feet 3, meters and the deepest point is the Puerto Rico Trench atfeet -8, what is a pqr in welding. The Atlantic Ocean is important to the world's hhe as are all oceans because strong Atlantic hurricanes often develop off the coast of Cape Verde, Africa and move toward the Caribbean Sea from August to November.
The Indian Ocean is the world's third-largest ocean te it has an area of 26, square miles 68, sq km. The Indian Ocean has whag average depth of 13, feet 3, meters and the Java Trench is its deepest point atfeet -7, meters. The Indian Ocean is known for causing the monsoonal weather patterns that dominate much of southeast Asia and for having waters that have been historical chokepoints narrow international waterways.
The Southern Ocean is the world's newest and fourth-largest ocean. In the spring ofthe International Hydrographic Organization decided to delimit a fifth ocean. In doing so, boundaries were taken from the Pacific, Atlantic, and Indian Oceans.
The Southern Ocean extends from the coast of Antarctica to 60 degrees south latitude. It has a total area of 7, square miles 20, sq km and an average depth ranging from 13, to 16, feet 4, to 5, meters.
The world's largest ocean current, the Antarctic Ard Current, moves east and is 13, miles 21, km in length. The Arctic Ocean is the world's smallest with an area of 5, square miles 14, sq km. It extends between Europe, Asia, and North America. Most of its waters are north of the Arctic Circle. Its average depth is 3, feet 1, meters and its deepest point is the Fram Basin atfeet -4, meters. Throughout most of the year, much of the Arctic Ocean is covered by a drifting polar icepack that is an average of ten feet three meters thick.
However, as the Earth's climate changes, the polar regions are warming and much of the icepack melts during the summer months. The Northwest Passage and the Northern Sea Route have historically been important areas of trade and exploration.

The oceans are the large masses of water bordering the continents. Even though they are all interlinked, they are predominantly categorized into five oceans as follows; Atlantic Ocean, Pacific Ocean, Indian Ocean, Antarctic Ocean, and the Arctic Ocean. Each of these oceans has distinctive characteristics.
Here are the details describing the five oceans of the world that provide a deeper comprehension of them. Atlantic Ocean is defined as the second largest ocean in the planet with an area of about ,, square kilometers. It is surrounded by Europe and Africa in the east and by America in the west.
The Atlantic Ocean was highly known as a voyage sea up to the 15 th Century thus having a historical marking for colonization and spice trade. It also spreads out to the Antarctic Ocean in the south and the Arctic Ocean in the north. The Atlantic Ocean is divided by the equator into north and south Atlantic. The area adjacent to the north of the equator, between South America and Africa, is termed as Central Atlantic. The water in this area is completely different from the waters in the northern part, which is between North America and Europe.
The ocean hosts many aquatic species including the sperm whale which is recorded as the largest living toothed creature. The Atlantic Ocean is also the saltiest of all the oceans and this salinity is mainly contributed by the process of precipitation, evaporation, sea ice melting and river inflow.
The water in the South Atlantic circulates in an anti-clockwise direction, whereas in the North Atlantic the circulation is in a clockwise direction. This phenomenon is owed to the Coriolis Effect. Some of the environmental concerns include endangered marine species such as seals, manatee, turtles, whales, and sea lions; driftnet fishing which leads to overfishing; municipal sludge pollution off southern Brazil, eastern U.
The Pacific Ocean is the largest of all the oceans. Its location is between the eastern coastlines of African and Asia and the western coastlines of the American landmass.
It is also bounded by the Antarctic Ocean in the south and the Arctic Ocean in the north. The Pacific Ocean extends to about ,, square kilometers and it also has the longest shoreline that totals to approximately , kilometers. The Pacific Ocean has very limited occurrences of damaging ocean currents or movements, which makes it a peaceful ocean. Some of the current environment concerns include endangered marine species such as the seals, whales, turtles, sea otter, dugong, and sea lion; and oil pollution in the South China Sea and the Philippine Sea.
The Indian Ocean is the third largest ocean on the planet. It covers an expanse of about 73,, square kilometers. Just like the Atlantic Ocean, the Indian Ocean was highly known as a voyage sea up to the 15 th Century that gave it a historical marking for colonization and spice trade. For this reason, the Indian Ocean has a great record of all sorts of humankind, all the way through world history.
The Indian Ocean is encircled by the eastern coast of Africa which constitutes the shores of the Middle East and India in the north.
Also, the Indian Ocean has plentiful exotic animal and plant species. Beach sands are also exploited by a majority of the countries bordering the Indian Ocean particularly because they are rich in heavy metals. The Indian Ocean is as well relatively warm compared to other oceans, which limits the growth of phytoplankton.
Gulfs, bays, and straits are also numerous within the spreads of this ocean. Some of the environmental concerns here include endangered marine species such as seals, whales, turtles, and dugong; and oil pollution in the Persian Gulf, Arabia Sea, and the Red Sea. The Antarctic Ocean is the fourth largest in the planet and only covers an area of about 20,, square kilometers. In the ocean zone, the warmer waters of the subantarctic mix with the cold northward flowing waters in the Antarctic.
Numerous kinds of marine animals live and depend on the phytoplankton in the Antarctic Ocean, making it an ocean rich in diverse marine species. Besides, the Antarctic Ocean is a depository of natural resources including valuable minerals and massive oil and gas fields.
The biggest environmental problems in the Southern Ocean are the impacts of global warming , overfishing, climate change , and ocean currents. The Arctic Ocean is the shallowest and smallest of all the oceans in the planet, more than five times smaller than the Atlantic and Indian oceans. Its surface area is about 13,, square kilometers and it mostly lies in the Arctic Circle. Most of the time throughout the year, the Arctic Ocean is covered with thick mountains of ice and it even remains impassable during summer.
The ocean is situated in the Northern Hemisphere and is commonly perceived to be the northernmost part of the entire World Ocean. Since ice cover freezes and melts occasionally, the surface temperatures and the salinity widely vary. Compared to the other oceans, its salinity is the lowest as it has limited connections to other oceans, a lower amount of evaporation, and a continuous inflow of fresh water from streams and rivers.
Plantlife are relatively little in the ocean. Phytoplanktons are common. Some of the pressing environmental issues in the Arctic Ocean include endangered marine species such as the whales and walruses; and a fragile ecosystem that slowly adjusts from damage or disturbance.
