Explain how soil is formed.
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. It is formed through the process of weathering.
Weathering is a process of physical breakdown and chemical decomposition of rocks and minerals near or at the surface of the earth.
This physical and chemical decomposition is primarily done by wind, water, and climate. As a result of these processes, large rock pieces are converted into smaller pieces and eventually to the soil.
[Extra information:
Soil is generally classified into the following:
1. Clay soil is defined as soil that is comprised of very fine mineral particles and not much organic material. The resulting soil is quite sticky since there is not much space between the mineral particles, and it does not drain well at all.
2. Sandy Soil contains a high percentage of sand or large soil particles. Water travels through sandy soil very easily, so nutrients leach out quickly.
3. Loam soil contains more nutrients, moisture, and humus than sandy soils. They have better drainage and infiltration of water and air. They are easier to till than clay soils. Loam soil is suitable for growing most plants.
