The second largest ocean on Earth is the Atlantic Ocean. Covering about 41 million square miles, it is bordered by the Americas to the west and Europe and Africa to the east. The Atlantic plays a significant role in global weather patterns and ocean currents, notably the Gulf Stream, which affects climates across the Atlantic coast of North America and Western Europe. It is also known for its rich biodiversity, shipping routes, and vital fisheries. The Atlantic Ocean's depth, size, and geological formations make it a key area for scientific research and exploration.
