Exogenic processes refer to the external forces and processes that shape and modify the Earth's surface, primarily through weathering, erosion, and deposition. These processes are driven by factors such as water, wind, ice, and gravity, and play a crucial role in shaping landscapes and landforms. Examples of exogenic processes include glaciation, river erosion, coastal erosion, and mass wasting events. Understanding these processes is important for studying the evolution of Earth's surface over geologic time scales and for predicting and mitigating natural hazards such as landslides and erosion.
