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.
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
