Weathering is the process where rocks are broken down into smaller pieces by forces like:

* Physical weathering: This involves forces like wind, water, ice, and temperature changes that physically break rocks apart.

* Chemical weathering: This involves chemical reactions that break down rocks, often by dissolving minerals or changing their composition.

Once the rocks are broken down, they become the foundation for soil. Further processes like the decomposition of organic matter, the movement of water, and the activities of living organisms contribute to the formation of soil.
