The correct answer is A. Wind erosion
Step-by-step explanation:
The soil is the substance that covers the surface of our planet, this is mainly formed as rocks break down which is called weathering. This phenomenon can occur due to the action of living organisms, due to chemical reactions or due to physical factors. In the case of physical factors, this includes collision, changes in temperature or pressure and wind erosion that occurs as the wind makes rocks and soil move and this movement can make rocks break down into smaller parts or become more prompt to break. Thus, one of the ways rocks can be broken down is through wind erosion.
