Oceans in the world...

  

An ocean is a body of water that is predominantly comprised of salt water. It covers nearly 70% of the Earth's surface. Oceans consists of slightly over 95% of all of the world's water. Oceans are also much larger and deeper that seas. There are five recognized oceans, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic oceans. 

Pacific Ocean 

The Pacific ocean is the world's largest ocean. It was named by the Portuguese explorer Ferdinand Magellan. It covers the one - third of the Earth. The Mariana Trench is the word's deepest trench with a depth of 11,033m is in Pacific ocean. The Pacific ocean covers 28% of the global surface which is roughly equivalent to all of the landmasses combined. It includes the Bali sea, Bering sea, Bering strait, Coral sea, East China sea, Gulf of Alaska, Gulf of Tonkin, Philippine sea, Sea of Japan, Sea of Okhotsk, South China sea, Tasman sea, and other tributary water bodies. 

Atlantic ocean

 

The Atlantic ocean is Earth's second largest ocean, covering roughly 17% of Earth's surface, it has shaped human history through exploration, trade, and colonization, following European's discoveries in the Age of Discovery. Along its margins, the Atlantic has several marginal seas that open into it. The Hudson bay, The Caribbean sea, The Mediterranean sea and The English Channel are all shallow seas that feed into the Atlantic ocean. 

Indian ocean

 The Indian ocean is the third largest ocean and the only one enclosed on three sides. Boarded by Africa, Asia and Australia the Indian ocean opens to the southern ocean, where it exchanges waters with the much colder body of water. The Indian ocean's warm waters and monsoon systems have a significant impact on regional and global climates, and it is a whiter component of the global oceanic system. 

Southern ocean (Antarctic)

 The Southern ocean, also known as The Antarctic ocean, is the newest addition to the list of the  world's oceans, officially recognized by the international hydrographic organization (IHO) in 2000. Unlike most oceans, a current separates the southern ocean from its neighbors, rather than land masses. The Antarctic circumpolar current (ACC) is the strongest current on the planet, carrying up to 182 million cubic meters of water every second. Spinning from west to east around the continent of Antarctica its flow separates the southern ocean from the saltier waters of the Atlantic, Pacific and Indian, carrying more than 100 times the flow of all the rivers on Earth. 

Arctic ocean 

  The Arctic ocean is a tiny, shallow ocean, compared to its giant friends. It covers for about 4% of the Earth's surface area. The Arctic ocean was a hot spot for sea exploration, as European explores and merchants were eager to find a northern sea route between the Atlantic and Pacific oceans, so they could more easily trade with Asia.
