1. wind action: wind blows away sand particles leaving a deep hollow. when the depression reaches the underground water it forms an oasis
2. glacial actions: when a glacier moves down hill, it erodes the areas it passes causing a depression.it filled with water to form lakes.e.g teleki
3. Faulting: depression occur on the floor of rift valley which collect water from rivers to form lakes.e.g bogoria
4. Down warping: the depression formed due to tensional forces collect water from rivers to form lakes. e.g lake Victoria
5. deposition: due to heavy load carried by the river, the meander become more pronounced forcing materials to be deposited on the sides eventually making some part to be cut off forming an ox-bow lakes
6. crater lake:are formed when water fills the depression at the top of volcanic mountain e.g lake shala
7. lava dammed lakes: formed when lava flows into a valley and blocks a river channel
