The world's second-largest ocean is the Atlantic Ocean, covering more than 41 million square miles. It extends from the Arctic Ocean in the north to the Southern Ocean in the south, separating the continents of North America and South America from Europe and Africa. The Atlantic Ocean is vital for global trade, as it hosts some of the world's busiest shipping routes and ports. Additionally, it plays a critical role in climate regulation through ocean currents, such as the Gulf Stream, which influences weather patterns. The Atlantic is also rich in biodiversity and resources, including fish and minerals.
