When a rock undergoes mechanical weathering, such as frost wedging, it breaks apart into smaller pieces. How does this process affect the rock’s total surface area

When a rock undergoes mechanical weathering, it is broken into smaller and smaller pieces, each retaining the characteristics of the original material, abut increasing the surface area available for chemical attack. Wind, glacial ice, rivers, and waves.

The surface area increases because new surfaces are exposed when the rock breaks apart.

This answer is correct!
