The Atlantic Ocean is the second-largest ocean in the world, covering about 20% of the Earth's surface. It stretches between the continents of North America and Europe to the north, and South America and Africa to the south. The ocean is known for its rich marine biodiversity and plays a crucial role in global weather patterns. The Atlantic Ocean is also significant for international trade, with major shipping routes connecting various countries. It contains several important features, including the Mid-Atlantic Ridge, which is an underwater mountain range, and the Bermuda Triangle, a region famous for mysterious disappearances.
