The second largest ocean in the world is the Atlantic Ocean, which covers an area of about 41 million square miles (106 million square kilometers). It is bordered by North America to the west, Europe and Africa to the east, and South America to the south. The Atlantic Ocean is significant not only for its size but also for its role in global trade, climate regulation, and biodiversity. It is home to various marine species, including fish, whales, and dolphins, and has several crucial marine ecosystems, such as coral reefs. Its depths also hold historical significance with numerous shipwrecks and underwater exploration.
