Summary:
- Weathering and erosion modify Earth's surface landscapes over time.
- Water erodes far more material than any other erosional agent.
- Wind is important as an agent of erosion in arid climates.
- Ice, in glaciers, can erode enormous quantities of sediments.
- Plate tectonics forces work to build huge mountains and other landscapes.
- Conversely, the forces of weathering gradually wear down those rocks and landscapes.
- Together with erosion, tall mountains turn into hills and even plains.
- Weathering breaks down Earth's materials into smaller pieces.
