Explanation:
How soils form
Soil is the thin layer of material covering the earth’s surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.
Most plants get their nutrients from the soil and they are the main source of food for humans, animals and birds. Therefore, most living things on land depend on soil for their existence.
Soil is a valuable resource that needs to be carefully managed as it is easily damaged, washed or blown away. If we understand soil and manage it properly, we will avoid destroying one of the essential building blocks of our environment and our food security.

Explanation:
Hi! There are several steps when it comes to soil formation.
The primary steps are:
- Weathering of rocks to form 'regolith' - an accumulation of rock debris above bedrock [parent rock.]
- Soil Profile formation
NOTE: The soil layer is largely affected by its parent rock. Ex: If the parent rock is sandstone, the soil would be sandy. Similarly, if the parent rock is made up of shale, the soil would be clayey.
