What helps the formation of soil?

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.

What are biotic and abiotic factors required in the formation of soil?

Soil formation can be both by biotic and biotic factors. Biotic factors includes biological i.e. living factors like plants, animals. … Human activities such as mining, digging also result in weathering and formation of soil. Abiotic factors means physical factors such as temperature, wind and water.

What are the biotic and abiotic factors in creating soil?

Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. … Other, less common minerals include calcium, magnesium, and sulfur. The biotic and abiotic factors in the soil are what make up the soil’s composition.

What is formed by biotic and abiotic factors and interactions with each other?
