A student wants to model the physical weathering of rock. Which activity could the student perform? (1 point)

Answer 1

The student could perform an activity involving the freezing and thawing of water in cracks of a rock. This process, known as freeze-thaw weathering, demonstrates how physical weathering occurs when water enters the cracks, freezes and expands, causing the rock to break apart over time. The student can collect small rocks, place them in a container, add water, and then place the container in a freezer. After freezing, the student can observe the effects on the rocks once they thaw, noting any changes or fractures that have occurred.
