Answer 1

The correct option is C mechanical and chemical breakup of rocks

When rocks are exposed to wind, rain, heat and frost, they break apart and crumble to form fine particles over a period of time. This process of mechanical and chemical break down of rocks is known as weathering. The fine particles formed due to weathering and erosion is known as soil. Soil is a supporter of life.
