Sunlight causes air to move, water to be lifted into mountains, and ocean waves to rise. Most of the landforms are formed and deformed due to the two processes, namely, endogenic that occurs within the earths crust such as convective heat cycles, rising plume, and magma chambers and exogenic processes that shape the features on the surface of the earth with the help of various agents of weathering like water, wind, glaciers.
