External Forces

EXTERNAL FORCES: External forces, or gradational forces, are forces acting from above on the surface of the Earth. They lead to slow and- steady changes on the face of the Earth, and include all the agents of gradation like wind, water and glaciers. They are also known as exogenetic forces or denudational forces.

The agents of gradation physically change the Earth’s surface by eroding (wearing away) land surfaces, transporting the eroded material and depositing the weathered soil, sand and other debris at other places. For example, rain, wind and river erode the mountains and highlands; the erode particles are carried and deposited further down to form plains
