Question

19. What is Soil? How can it be formed

​

Answer 1

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.

Answer 2

Answer:

Soil is the  mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things.

Explanation:. They are produced from rocks  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.

                                                    or

 Soil is formed from the weathering of rocks. Rocks are broken into several fine pieces due to temperature, rainfall and organic materials over a period of time.

It takes millions of years for the formation of soil.
