Exogenic processes are physical processes that create and modify landforms on the surface of the Earth. These processes are classified into two categories: endogenic processes and exogenic processes. Endogenic processes are those that originate within the Earth, while exogenic processes are those that derive their strength from the Earths exterior or originate within the Earths atmosphere. Exogenic processes are also known as external forces or exogenic forces.

Exogenic processes are covered under a general term called denudation, which means strip off or uncovers. The main exogenic processes are weathering, mass wasting, erosion, and deposition. The elements of nature capable of doing these exogenic processes are termed geomorphic agents or exogenic geomorphic agents, such as wind, water, waves, and people.

In summary, exogenic processes are physical processes that occur on the Earths surface due to the influence of external forces, and they create and modify landforms. They are classified into different types, including weathering, mass wasting, erosion, and deposition, and are covered under the general term denudation.
