How is soil formed?
Answers
Answer:
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.
Answer:
Soil is formed by breaking down of rocks at or near the surface of the Earth through various physical, chemical, and biological processes by various factors such as the sun, water, wind, and living organisms. These cracks lead to the breaking up of huge rocks into smaller pieces.
Explanation:
Soil is formed from he 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.
Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three size classes — clay, silt, and sand (Figure 1); the percentages of particles in these size classes is called soil texture.
