D Place several cookies in a box, and then shake the box is the activity that best models the physical weathering of rock. Physical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition. Shaking the box with cookies represents the mechanical force that causes rocks to break apart into smaller fragments.
