This document discusses various exogenic (surface) processes that shape the Earth's surface through erosion and weathering. It describes different types of physical and chemical weathering that break down rock material. Erosion by water, wind, ice and gravity is then able to transport this weathered material. Mass wasting specifically refers to the movement of this loosened material down slopes due to gravity, which can occur through sliding, flowing or falling. The material is eventually deposited through sedimentation.
