How does the Sun contribute to physical weathering?

A. When water is heated, it expands, which causes rocks to break.

B. Minerals in rocks heat and expand at different rates, which causes rocks to break.

C. The Sun has no effect on the physical weathering of rocks.

Answer: B

Explanation:

Just took this.

B. Minerals in rocks heat and expand at different rates, which causes rocks to break.

Explanation:

Weathering is the process of transformation and wear of rocks and soils, through chemical, physical and biological processes. Its dynamics happens through the action of so-called exogenous or external agents of transformation of relief, such as water, wind, temperature and living beings.

Temperature is a factor that causes the physical wear and tear of rocks through the action of the sun. In this process, the minerals in the rocks heat up and expand at different rates, which causes the rocks to break.

The heat of the Sun reduces the amplitude of the relief as climatic mechanisms cause mechanical and chemical transformations, translated into weathering processes, which form new minerals and break up rocks, and erosion and sedimentation, which sculpt and mold new forms of relief.
