-Gradational processes are responsible for the reduction of land surface.
Explanation:
-Gradational processes are responsible for the reduction of land surface. If a land surface where a mountain once stood is now a low, flat plain, gradational processes have been at work. The worn, scraped, or blown away material is deposited in new places and, as a result, new landforms are created
-Volcanism is the force that transports heated material to or toward the surface of the earth
