A more thorough explanation:

A lake is a large body of water that is located in a depression or basin on the surface of the earth. It is usually supplied by the drainage of an extended area and is substantially at rest.

For example, the Great Lakes in North America are a group of five large lakes that were formed by glaciers during the last ice age. They are located in a depression and are supplied by the drainage of an extended area.

Another example is Lake Baikal in Russia, which is the deepest lake in the world. It is located in a basin and is supplied by the drainage of an extended area.

Overall, lakes are important bodies of water that provide habitats for various aquatic plants and animals. They also serve as sources of drinking water and are used for recreational activities such as swimming and fishing.
