The Atlantic Ocean has a surface area of 106,400,000 sq kms which covers 20% of the earth's surface and contains 26% of the earth's salt water at 354,700,000 cubic kilometres. The Ocean's deepest point is at the point of the Puerto Rico Trench at a depth of 8,605 metres.
The name Atlantic, originally Atlantikos, comes from the ancient Greek word meaning Atlas Sea. The ocean can also be seen on some old maps as the Aethiopian or Ethiopian Sea.
The ocean's main feature is the 65,000 km long by 1,600 km wide, Mid - Atlantic Ridge, a vast underwater mountain range which borders several tectonic plates, along the entire length of the ocean floor, from Bouvet Island to it's south travelling northwards through the country of Iceland and on to Jan Mayan island to it's north.
Norway's tiny volcanic, Bouvet Island, the world's remotest island situated 2,525 kms from it's nearest neighbour, South Africa, is the most southerly landmass situated on the ridge and Norway's Jan Mayan Island is the most northerly landmass situated on the ridge.
The Mid - Atlantic Ridge divides the ocean into east and west and the point of the Equator divides the ocean into north and south.
THE MID - ATLANTIC RIDGE
The Atlantic Ocean is linked to the Pacific Ocean at the point of Drakes Passage at the very southern tip of South America and the Panama Canal, situated at Central America's narrowest point on the Isthmus of Panama.
The Atlantic links with the Arctic Ocean by way of the Greenland Sea and Labrador Sea situated off Canada's northern coast and the Denmark Strait and Norwegian Sea in Northern Europe.
The Atlantic is linked to the Mediterranean Sea in Europe at the point of the Straits of Gibraltar situated between the Iberian Peninsular and North Africa and linked to the North Sea by way of the Denmark Straits.
The Atlantic flows into the Indian Ocean at the point of the 20th Meridian East.
The Atlantic Ocean is bordered by the Arctic Ocean to it's north and the Southern Ocean to it's south and has coastlines on 65 countries on four continents, 15 in Europe, 27 in Africa, 11 in South America and 12 in North America.
The Atlantic Ocean consists of thousands of gulfs and bays, including the vast Gulf of Guinea situated off the west coast of Africa, the Bay of Biscay, situated off France's west coast, Canada's Hudson Bay, the world's largest bay at 4,041,400 sq kms and the U.S.A's Bay of Fundy, which has the world's highest tidal range with a mean spring tide of between 14.5 metres and 16.3 metres.
