Lakes are often temporary features on a geological timescale, created by glacial, tectonic, or volcanic processes, and eventually filled in by sedimentation.
Lakes are generally divided into four distinct zones based on physical, chemical, and biological characteristics:
Deepest lakes, such as Lake Baikal, often fill a graben (a rift between fault lines).
