The process in which small pieces of rock are worn away from larger rocks is called weathering.

Quick Scoop

Weathering is the natural process that breaks big rocks into smaller pieces over time.

It happens because of things like wind, water, ice, temperature changes, and even plants and animals acting on the rock’s surface.

In many school science questions, when you see “small pieces of rocks are worn away from larger rocks,” the expected name of the process is weathering rather than erosion, because the focus is on breaking the rock apart, not on transporting the pieces away.

TL;DR: The name of the process is weathering.
