Final answer:
The two forces that drive the rock cycle on Earth are weathering and erosion.
Step-by-step explanation:
The two forces that drive the rock cycle on Earth are weathering and erosion.
Weathering involves the breaking down of rocks into smaller pieces through physical or chemical processes. This can occur through things like freeze-thaw cycles, plant roots growing into cracks, or acid rain. Erosion, on the other hand, involves the movement of these weathered rock pieces by forces like wind, water, or ice. This can lead to the transportation and deposition of sediment in different areas, which is an important part of the rock cycle.
