what is erosion in geography

Erosion in geography refers to the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. It is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock's chemical composition changes, while physical erosion describes the process of rocks changing their physical properties without changing their basic chemical composition. Erosion is a significant environmental problem worldwide, and human activities such as intensive agriculture, deforestation, and urban sprawl can stimulate erosion. However, there are prevention and remediation practices that can curtail or limit erosion of vulnerable soils
