Final answer:
The subprocesses within erosion are weathering, transport, and deposition. These processes shape the earth's surface by breaking down materials, transporting them, and then depositing them in new locations.
Step-by-step explanation:
Subprocesses within erosion include weathering, transport, and deposition. Weathering is the process that breaks down existing Earth materials, which can then be transported by forces such as water, wind, or ice. Transport refers to the moving of eroded material from one location to another, and deposition is the settling or laying down of these materials in a new location. In erosion and its subprocesses, rocks and sediments are worn down and shaped, with their fragments being transported and eventually deposited to form new landforms.
