- : The Atlantic Ocean covers about 20% of the Earth's surface. This ocean is the second largest ocean in the world's oceans. The oceans are bounded by landmasses in the west to North and South America and east to Asia and Africa. It is located on the north side of the ocean, the southern ocean on the south, the Pacific in the southwest, and the Indian Ocean in the southeast. The Atlantic Ocean is the deepest point.
- : The surface area of the Atlantic Ocean is 106,460,000 km2 (41,100,000 sq mi) and the North Atlantic surface is 41,490,000 km2 (16,020,000 sq mi) and the South Atlantic surface is 40,270,000 km2 (15,550,000 sq mi). The average depth of the ocean is 3,646 meters and the maximum depth is 8,376 meters. The water content of the Atlantic Ocean is 310,410,900 km3 (74,471,500 cu mi) and the coast length is 111,866 km.
- : The ocean's S-shaped basin extends eastward into Europe and Africa, and from America to the west. The Atlantic Ocean is so vast that its climate varies from north to south. The Gulf Stream and North Atlantic Drift are responsible for keeping most parts of north-western Europe and the British Isles warm when the coast of Newfoundland experiences extreme temperatures in Canada at the same latitude in the Atlantic Ocean.
- : The major contributing to the economy of many countries is the ocean. There are abundant petroleum deposits, precious stones, placer deposits and polymetallic nodules on the floor of the Atlantic Ocean. Herring is a commercially important fish species in this ocean.
- : Many rare and endangered species of marine life, such as sea turtles, whales, dolphins, manatees, seals, sea lions, live in the Atlantic Ocean. These oceans often endanger marine life because of oil spills, municipal sewage pollution, and industrial pollution, irresponsible and outdated fishing activities.
- : The oldest mention of the Atlantic Sea refers to the "sea beyond the pillars of Heracles" in the histories of the sixth-century Atlantic Pelagic and BC around BC. It is the part of the ocean that surrounds all the land. These appeared in the medieval map as fronts. The original meaning of the word Atlantic is mentioned specifically in the Atlas Mountains of Morocco and the Sea of Gibraltar and the coast of North Africa.
- : In the 19th century the term Ethiopian origin was applied to the southern Atlantic in the central part of the "Ethiopian Ocean". In ancient times Atlantic was known to English cartographers as the Great Western Ocean. In 1953, the international hydrographic ocean and ocean boundary were determined. Some of those definitions have been modified because some are not used by various authorities, organizations, and countries, for example the CIA. World Factbook. Accordingly, the extent and number of oceans and oceans vary.
- : The ocean is connected by the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea and to the east by the Strait of Gibraltar. The ocean merges in the southeast Atlantic Indian Ocean. In the map after 1953 the South Ocean is bounded at 60 °. This ocean contains irregular seas indented by numerous creeks, gulfs and oceans.
