â¢ Erosion and deposition are continuous geological processes that are natural and result in relief features seen over the surface of the earth. â¢ If erosion is seen as a sequence of events, deposition takes place at last when the rock particles finally settle down on the surface of earth.
A delta is a feature of deposition, located at the mouth of a river as it enters a sea or lake. Deposition occurs as the velocity and sediment-carrying capacity of the river decrease on entering the lake or sea, and bedload and suspended material are dumped.
