Where does Erosion and Deposition occur in a river?
Deposition occurs as the moving river picks up soil and moves it downstream. Erosion occurs when the river currents slow as it enters the larger body of water and drops the soil.
The river is eroding the land. There is no deposition.
The delta forming at the mouth of the river is from deposition. There is no erosion.
Erosion occurs as the moving river picks up soil and moves it downstream. Deposition occurs when the river currents slow as it enters the larger body of water and drops the soil.
Erosion is defined as the ❌ of ❌ material from one location to ❌. Deposition is defined as the ❌ down or settling of ❌ material.
