Lakes are large bodies of water surrounded by land, and they can be found in various environments around the world. They play a crucial role in the ecosystem, providing habitats for numerous species of fish, birds, and other wildlife. Lakes can be formed through various geological processes, including glacial activity, volcanic eruptions, and tectonic movements. In addition to their ecological importance, lakes are also vital for human activities. They serve as sources of drinking water, recreational areas, and sites for fishing and boating. Some well-known lakes, such as Lake Baikal and Lake Superior, are famous for their size and unique characteristics.
