What causes erosion?

• A. Erosion
• B. Weathering
• C. Deposition
• D. Gravity

Answer: (D)

Erosion is the process of removing and transporting rock and soil from one place to another by natural forces. The force that actually moves material downslope is gravity. When rock and soil are loosened by weathering, gravity pulls them downward, and water, wind, or ice can then carry that material away. Gravity-driven processes such as landslides, rockfalls, and mudflows illustrate erosion powered by the downward pull of gravity. Weathering causes the breakup, deposition is where transported material settles, and erosion is the overall transport; gravity provides the key force that initiates and sustains that movement.
