Answer:
C. Moves bits of rock and soil
Step-by-step explanation:
The erosion is the process that is moving away material from its original location. This process is directly connected and dependent on the weathering, as the weathering is the process that manages to break up the material, so that the erosion is picking it up and moving it away. The process that follows the erosion is the deposition, which is depositing of the eroded material in another location.
The erosion as a process has a tendency to lower and flatten the land forms, so it is a limiting factor as to how much a land form can alleviate, or how much it will last. Some things prevent or minimize the erosion, especially the vegetation, while some things like the intense rainfall and strong winds are speeding up this process, especially if the land is barren.
