The rocks that compose the Earth's crust are subjected to a variety of forces. Depending on the environmental factors at work, the rocks can be altered in size or in composition. Factors such as wind, water, plants, and animals cause weathering, physical changes in rocks that affect their size. However, physical changes do not affect the composition of rock. In this activity you will see the effect of physical weathering on rocks.
