GENERAL GEOLOGY

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: -Two forces, weathering and erosion, are constantly at work building up and moving rocks making up the Earth’s crust. Weathering causes rocks to fragment, crack, crumble, or break down physically and chemically. Erosion loosens and carries away the rock debris formed by weathering.

Detailed explanation-3: -A geomorphic landscape is an area defined by a distinctive set of landforms produced by a distinctive set of geomorphic processes, for example, a riverine, arid or coastal landscape.

Detailed explanation-4: -Geomorphology is the study of landforms and landform evolution. The topic traditionally has been studied both qualitatively, which is the description of landforms, and quantitatively, which is process-based and describes forces acting on Earth’s surface to produce landforms and landform change.
