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.
Deepest lakes, such as Lake Baikal, often fill a graben (a rift between fault lines).
A new dataset offers detailed 3D bathymetry for 510,530 global lakes, representing 98.9% of global surface water storage. Lakes and Reservoirs | U.S. Geological Survey - USGS.gov Lakes are complex, dynamic ecosystems that act as

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

Deep lakes often form a three-layered structure in summer: a warm upper layer ( epilimnion ), a middle transition layer ( metalimnion ), and a cold bottom layer ( hypolimnion ).
