Concept:Denudation is the overall process that lowers and levels the earth’s surface.
Explanation:The process described involves gradual breaking and wearing away of the earth’s surface, which leads to lowering and levelling.
Weathering only breaks rocks in place, while mass wasting involves downslope movement of material.
Relief refers to the shape and height of the land, not a process.
Denudation is the broad term that includes weathering, erosion, and transportation by agents such as water and wind, all acting together to wear down and level the surface.
