(i) Lake formed due to faulting
Faulting due to tectonic forces may lead to uneven displacement of land
Some parts sink and tilt along the faults
It results in long, narrow, steep-sided depression along the fault lines
Faulting may result in depression on the floor of the rift valley as land adjusts
Such depressions are shallow
The depression fill water from rain/underground to form rift valleys lakes
(ii) Crater lakes
Craters/calderas form during vulcanicity on a volcano or at ground level
When lava cools, the magma in the vent contracts/pressure leads to explosion/ a crater due to a falling meteorite
Rain water and melting snow may collect in the crater to form a crater lake, e.g. L. Paradise on Mt. Marsabit, Crater Lake on Central Island of L. Turkana.
