B. Bigger rocks being broken down into smaller pieces using physical means such as frost wedging, exfoliation, abrasion, impact, and roots from plants.

Mechanical (or physical) weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition. This process can occur through various physical forces, including temperature changes, freeze-thaw cycles, the growth of plant roots, and the impact of wind, water, or ice.
