A lake is a large body of natural water accumulated in a depression. Lake basins are formed due to endogenous geological processes like tectonism and volcanism and exogenous activities like landslides, glaciation, solution, river and wind action.
Classification of LakesLakes are classified based on size, shape, depth and mode of formation.
Tectonic LakesThese lakes are formed due to the folding and faulting of plates in earth's Crust. Caspian Sea, Lake Baikal, Tso Moriri and Pangong Tso (Ladakh) are some examples of such lakes.
Crater LakesThese lakes are formed when caldera and craters are filled with water. Lonar lake in Maharashtra is one such example.
A caldera or crater is a large hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption.
When large volumes of magma erupt over a short time, structural support for the rock above the magma chamber is lost. The ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a massive depression at the surface.
Glacial LakeThese lakes are formed to the erosion/melting of glaciers. They are formed when a glacier erodes the land, and then melts, filling the depression created by the glacier.
Most of the glacial lakes are found in the Himalayan region in India.
Ox-Bow LakesAn oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water
It is formed due to the depositional and erosional activities of the River.
LagoonsA lagoon is a shallow body of water protected from a larger body of water (usually the ocean) by sandbars, barrier islands, or coral reefs. Lagoons are often called estuaries, sounds, bays, or even lakes.
Chilika Lake, Pulicat Lake are some of the examples.
Artificial LakesFormed by Humans for recreational, hydrological, ecological, economical purposes.
