Lakes are large bodies of standing water surrounded by land. They may be freshwater or saline, and they are formed due to tectonic activity, glacial erosion, river action, volcanic activity, or human construction. Lakes are important for water supply, irrigation, biodiversity, tourism, fisheries, and climate regulation.
