Discover the beauty and diversity of lakes, from glacial wonders to volcanic craters. Learn about rift lakes, oxbow lakes, and more fascinating formations worldwide. Let’s dive into the wonders of these inland bodies of water.

Lake • A lake is a body of water which is inland, not part of the ocean, is larger and deeper than a pond, and is fed by a river.
Lakes • Most lakes have a natural in the form of a river or stream, but some do not and lose water solely by evaporation or underground seepage or both.
Salt lakes • Salt lakes can form where there is no natural outlet or where the water evaporates rapidly and the drainage surface of the water table has a higher-than-normal salt content.
Types of lakes • Types of lakes by basin formation
Rift lakes • A rift lake is a lake formed as a result of subsidence related to movement on faults within a rift zone, an area of extensional tectonics in the continental crust. • They are often found within rift valleys and may be very deep.
Crater lake • A lake which forms in a volcanic caldera or crater after the volcano has been inactive for some time
Glacial lake • A glacial lake is a lake with origins in a melted glacier • Most Estonian lakes are glacial lakes
Oxbow lake • A lake which is formed when a wide meander from a stream or a river is cut off to form a lake
Oxbow lake Meanders and oxbow lakes on the Nowitna River, Alaska
Thermokarst lakes • A body of freshwater, usually shallow, that is formed in a depression by meltwater from thawing permafrost
Artificial lake • A lake created by flooding land behind a dam
Subglacial lake • A subglacial lake is a lake under a glacier Lake Vostok
