De Atlantic Ocean be de second largest of de world ein five oceanic divisions, plus an area of about 85,133,000 square kilometers (32,870,000 sq mi).[1] E dey cover approximately 17% of Earth ein surface den about 24% of ein water surface area. During de Age of Discovery, na e be known for separating de New World of de Americas (North America den South America) from de Old World of Afro-Eurasia (Africa, Asia, den Europe).

De ocean remain a core component of trade around de world.

De Atlantic Ocean ein temperatures vary by location. For example, de South Atlantic dey maintain warm temperatures year-round, as ein basin countries be tropical. De North Atlantic maintain a temperate climate, as ein basin countries be temperate wey e get seasons of extremely low temperatures den high temperatures.[2]

De Atlantic Ocean dey occupy an elongated, S-shaped basin wey dey extend longitudinally between Europe den Africa to de east, den de Americas to de west. As one component of de interconnected World Ocean, e be connected insyd de north to de Arctic Ocean, to de Pacific Ocean insyd de southwest, de Indian Ocean insyd de southeast, den de Southern Ocean insyd de south. Oda definitions describe de Atlantic as extending southward to Antarctica. Dem divide de Atlantic Ocean insyd two parts, de northern den southern Atlantic, by de Equator.[3]
