Explanation
Lakes are usually formed in rift zones, melting glaciated areas, mountainous regions, or in basins where rivers flow. On a geologic time scale, all lakes are transitory. Over time, lakes may run out of water caused by spillage or may be filled in with sediments. However, active processes may delay a lake from drying up, such as lakes with tectonic origins, meaning they formed in a rift zone where tectonic plates collide. Some factors that cause lakes to form are landslides, sinkholes, ice-damming, volcanic eruptions, and glacier movements. Lakes also vary greatly in size, shape, and depth. The depth of lakes is measured using two parameters: the maximum depth (the distance from the surface to the deepest point in the lake) and mean depth (average depth of the lake).
