Concept:Denudation is the wearing away of the Earth's surface through a definite sequence of processes.
Explanation:Denudation occurs in stages that usually follow one another.
The main stages are weathering, erosion, transportation, and deposition.
Weathering breaks down rocks in place.
Erosion carries away the broken materials.
Transportation moves these materials to new locations.
Deposition drops or settles the transported materials.
Decomposition is not a separate stage of this sequence.
It is actually a part of chemical weathering, not one of the listed sequence of denudation.
Therefore, decomposition is the odd one out among the given options.
Answer:C. Decomposition
