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 agents of erosion lay down sediment, deposition occurs. Deposition changes the. shape of the land. Weathering, erosion, and deposition act together in a cycle that wears down and. builds up Earth's surface. This cycle, called the geologic cycle, has continued for billions of years.
