What is the process that wears down rocks and carries away sediments by wind, water, or ice?

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

Answer: (A)

Erosion is the process that wears down rocks and carries away sediments by wind, water, or ice. It shows both breaking down of material and its movement to new places, often after weathering has already started the rock breakdown. This transport by rivers, wind-blown dust, or glacier movement shapes landscapes like valleys, coastlines, and canyons. Weathering is the in-place breakdown of rock, transportation is the act of moving sediment, and deposition is when that sediment settles elsewhere. So erosion best fits the description of both wearing down rocks and moving the resulting material.
