A lake is a large water body that is surrounded by land. Lakes are inland, i.e., not part of the world's oceans. Most lakes are situated in places with ongoing glaciations, rift zones and in mountainous regions. These lakes are drained and fed by numerous streams and rivers. The largest lake on Earth is the Caspian Sea. However, as its name would suggest, the Caspian Sea is sometimes classified as a sea and not a lake. In these cases, Lake Superior would be the largest lake in the world.
