The Atlantic Ocean is the second-largest ocean in the world, covering about 20% of the Earth's surface. It stretches between the Americas to the west and Europe and Africa to the east. The ocean is known for its rich biodiversity, including various species of fish, marine mammals, and coral reefs. The Atlantic Ocean plays a crucial role in global weather patterns and ocean currents, such as the Gulf Stream, which helps regulate temperatures in Europe. It also serves as a vital route for international trade, connecting major ports and facilitating the movement of goods across continents.
