Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

How is soil created from rock?

Soil is formed through the process of rock weathering. Weathering is the breakdown of rocks into smaller particles when in contact with water (flowing through rocks), air or living organisms. ... This acidifies water in rocks leading to further chemical reaction with rock minerals.

What is the origin of most soils?

 Soil consists largely of mineral matter formed by the disintegration or decomposition of rocks. This disintegration into soil may be caused by the action of water, ice, frost, or temperature changes, or by plant or animal life. Almost all soils contain water in varying amounts and in free or absorbed form.
