Concept:Denudation is the overall process that lowers and levels the earth's surface through gradual wear.
Explanation:The question describes both "breaking" and "wearing away" of the earth's surface until it becomes level.
Weathering alone only breaks rocks in place; it does not lower or level the land.
Mass wasting is simply the downslope movement of materials under gravity, not general levelling.
Relief refers to the shape or form of the land, so it is not a process at all.
Denudation is the collective term for weathering, erosion, and transportation working together.
Agents such as running water, wind, ice, and waves gradually break and wear down the surface.
This continuous action slowly lowers and levels the earth's surface over time.
Hence, the correct answer is denudation.
Answer:B. Denudation
