Which statement best describes erosion?

• A. Erosion wears down rocks, transports sediments, and deposits them elsewhere.
• B. Erosion creates magma in the crust.
• C. Erosion forms fossils.
• D. Erosion transforms sedimentary rock into metamorphic.

Answer: (A)

Erosion is the process that removes material from Earth’s surface and moves it to new locations. It starts with weathering that breaks rocks into smaller pieces, then uses agents like water, wind, ice, and gravity to transport those sediments and eventually deposit them elsewhere. This movement and settling shape landscapes, carving valleys and building features like beaches and deltas. The other statements describe things erosion isn’t responsible for: magma forms by melting rocks deep in the crust or mantle, fossils are preserved remains from ancient life (erosion may reveal them but doesn’t create them), and metamorphic transformation changes rock minerals under heat and pressure, not through erosion.
