Which of the following is NOT a factor of 'Soil formation'?

Explanation

The correct answer isRole of inorganic material. Key Points The material that covers the earth's surface , known as soil, is created as a result of rock weathering . It's primarily composed of mineral atoms, organic substances, air, water, and living things, all of which interact slowly yet continuously. It takes two steps to generate soil: The weathering of rocks occurs . Small fragments of rock are produced. Soil is created when these tiny particles combine with humus, an organic substance. The parent material, which determines the mineral content and greatly influences the chemical and physical qualities of the soil, is the first step in the soil formation process. Materials that are incorporated into the soil, such as new mineral materials deposited by wind or water or organic matter (OM) , which is composed of decaying plants and other living things. Sand, silt, clay, and OM are examples of soil particles that can be eroded, leached, or harvested from the soil by wind, water, or plant uptake , changing the chemical and physical composition of the soil. Sand is chemically weathered, clay minerals are formed, and coarse organic matter is transformed into decay-resistant organic compounds. Mineral or organic soil components moving between layers or within the profile. This process becomes one of the more observably prominent ones over time as changes in color, texture, and structure become obvious.
