Erosion

Two processes that have slight differences: Erosion wears down the earth, while weathering weakens rock or breaks it down into smaller pieces. No rock can withstand these forces, and that’s what has shaped our planet.

See how water, wind, and ice formed several natural wonders and learn the role people play in changing the landscape.
