Weathering, mass wasting, erosion and transportation are indicators of which one of the following processes?
Explanation
The processes of weathering, mass wasting, erosion, and transportation are collectively referred to as denudation [4]. These are exogenic geomorphic processes driven by forces emanating from above the Earth's surface, primarily powered by solar energy and gravity [5]. While weathering involves the mechanical or chemical breakdown of rocks, erosion involves the acquisition and transportation of rock debris by agents like water, wind, and ice [5]. These processes work in tandem to wear down the Earth's relief, a phenomenon known as degradation [5]. In contrast, endogenetic processes like diastrophism and volcanism are internal forces that build up or elevate the Earth's crust [6]. Therefore, denudation is the general term that encompasses all exogenic processes that strip away the Earth's surface [4].
