Final answer:
False, Mass wasting is not the second step in the three-step system of denudation; it is the first step, followed by erosion and deposition.
Step-by-step explanation:
This is false, as mass wasting is the first step. Denudation is the process of wearing away the Earth's surface by various processes including weathering, mass wasting, and erosion. Mass wasting refers to the downslope movement of soil and rock under the influence of gravity. It does not come after erosion (the second step), which often involves the transportation of material by water, wind, or ice. The third step involves the deposition of the carried material in new locations.
