Lakes are some of the most interesting natural features on our planet. They shape the land around them, affect local weather and provide homes for many plants and animals. Some lakes are so large that they look like seas and stretch across several countries, supporting millions of people. These huge water bodies are important for fishing, farming, transport and even cultural traditions. Whether they contain freshwater or saltwater, lakes help us understand how Earth has changed over time. Learning about the world's largest lakes gives us a better picture of the natural forces that continue to shape life on our planet.
The Largest Lakes In The World By Surface Area
1. Caspian Sea - 371,000 square kilometres
Although known as a "sea," the Caspian Sea is technically the world's largest lake because it is completely surrounded by land. It spans five countries: Kazakhstan, Turkmenistan, Azerbaijan, Russia and Iran, making it a key economic and geopolitical region. Its waters are mildly salty and contain rare species such as the endangered Caspian seal. The Caspian's enormous size makes it larger than many nations.
