Describe How Soil Forms?

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.

Describe How Soil Forms?

Soil formation, or pedogenesis, is the process by which loose unconsolidated material is transformed into a soil. The process involves the breakdown of minerals and organic matter, the alteration of the soil structure and chemistry, and the development of soil horizons. Soil formation is the result of natural forces such as weathering, erosion, and biological activity.

Soil formation begins with the breakdown of rocks into smaller particles. This process is known as weathering, and it occurs in both mechanical and chemical forms. Mechanical weathering involves the physical breakdown of rocks into smaller pieces;

this process is most often caused by the freeze-thaw cycle, as water enters cracks in the rocks and then expands when it freezes, causing them to break apart. Chemical weathering involves the dissolution of minerals by chemical reactions, such as acid-base or oxidation-reduction reactions. Organic matter, such as decaying plants, can also contribute to the breakdown of rocks.

The breakdown of rocks and organic matter results in a layer of loose material, known as regolith. This material is then further broken down by the actions of organisms such as bacteria, fungi, and worms. They break down the organic matter and mix it with the mineral particles, creating a mixture of organic and
