Question

what is soil formation ​

Answer 1

Answer:

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.

(i) Addition of mineral and organic matter to the soil. (ii) Losses of mineral and organic matter from soil. (iii) Translocation of mineral and organic matter from one point of soil profile and deposited at another horizon. (iv) Transformation of mineral and organic matter in the soil and formation of definite layers.

The whole soil, from the surface to its lowest depths, develops naturally as a result of these five factors. The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time
