explain the different types weathering that takes place during the formation of soil?
Answers
Answer:
There are three main types of weathering; physical, chemical and biological. Physical weathering is the influence of processes such as freezing and thawing, wetting and drying, and shrinking and swelling on rocks and other sediments, leading to their breakdown into finer and finer particles.
Explanation:
Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. 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 particles .these small particles mix with humus (organic matter) and form soil.
The basic components of soil are minerals, organic matter, water, and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air.
