Concept:Weathering is the gradual breakdown of rocks in situ by physical or chemical processes.
Explanation:Erosion is not correct because it involves the removal and transport of rock particles by agents like water, wind, or ice.
Denudation is a broader term that refers to the lowering of the land surface due to weathering and erosion combined.
Deposition is the opposite process, where eroded materials are dropped or laid down in a new location.
Weathering is the breaking down of rocks at their original position without movement.
It can happen through physical processes such as temperature changes and frost action.
It can also happen through chemical processes such as oxidation and carbonation.
Since the question specifically mentions breakdown "in situ," the correct answer is weathering.
Answer:C. Weathering
