Which process breaks rocks into smaller pieces?

Which process breaks rocks into smaller pieces?

• A. Weathering
• B. Erosion
• C. Melting
• D. Freezing

Answer: (A)

Weathering is the process that breaks rocks into smaller pieces at or near the surface. It happens through physical forces like freeze-thaw cycles, abrasion, and plant roots, as well as chemical reactions that weaken rock. The result is fragments that can later be transported or dissolved. Erosion, in contrast, moves those pieces away from their original location. Melting turns rock into liquid, not pieces, and freezing is a mechanism that can drive physical weathering, but the broad process that produces smaller fragments is weathering.
