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.
When the upcurrent amount of sediment is less than the amount being carried away, erosion occurs. When the upcurrent amount of sediment is greater, sand or gravel banks will tend to form as a result of deposition.
