The correct distinction between weathering and erosion is: Erosion breaks down rocks and moves particles, while weathering is only the breakdown of rocks.
Weathering refers to the process by which rocks are broken down into smaller pieces due to various factors such as temperature changes, water, chemicals, and biological activity. Erosion, on the other hand, involves the movement of those weathered materials from one location to another, usually by water, wind, ice, or gravity.
