Describe how plants, wind, and ice can
cause physical weathering.

Explanation:

Physical weathering, also known as mechanical weather, is the process of rocks and minerals on Earth's surface breaking down or dissolving as a result of water, ice, salt, plants, animals or changes in temperature. Physical weathering does not change the chemical composition of the rock, just cracks and crumbles it into smaller pieces. After a rock has weathered, erosion occurs, transporting bits and pieces away. Finally a deposition process deposits the rock particles in a new place.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
