Detailed explanation-1: -Weathering, mass wasting, erosion and deposition are exogenic geomorphic processes. These exogenic processes are dealt with in detail in this chapter. Any exogenic element of nature (like water, ice, wind, etc., ) capable of acquiring and transporting earth materials can be called a geomorphic agent.

Detailed explanation-2: -Tectonic plate movement under Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.

Detailed explanation-3: -The Earth’s surface is constantly forming and reshaping due to the combined occurrence of weathering and erosion. These two processes give rise to the formation of a variety of landforms. Some of the landforms created by fluvial erosion include river valleys, oxbow lakes, waterfalls, sinkholes, and caves.
