Lakes are often temporary features on a geological timescale, created by glacial, tectonic, or volcanic processes, and eventually filled in by sedimentation. created by glacial

Lakes are complex, dynamic ecosystems that act as critical components of the Earth's hydrological and biogeochemical cycles. As integral parts of the landscape, they store surface water, regulate local climates, and support diverse ecosystems. or volcanic processes

Lakes are generally divided into four distinct zones based on physical, chemical, and biological characteristics:
