The soil is not only an important natural resource for humans but it also provides a habitat for living organisms such as plants and animals.Soil can be classified based on the size or type of particles that compose it. Clay soil has very small particles while sand has larger particles.The texture of the soil determines what kind of plant life will grow in the area. For example, sandy soils are unsuitable for most plants because there are not enough nutrients or organic matter to sustain them.How Soil is FormedSoil is formed by the joining of organic and inorganic matter. Organic matter includes decomposing plant and animal tissues, while inorganic material includes clay, silt, sand, and various minerals.Soil is something that we don’t think about too often. It’s hidden under our feet and we don’t have to worry about it until it’s not there anymore. But the soil that forms a surface layer of earth is full of life-giving nutrients for plants to grow on. The soil below the surface layer has a completely different life cycle. It usually takes a lot longer for this soil to break down because it’s so far away from any oxygen-rich areas such as roots or leaves, but this makes it an important part of nutrients cycling in an ecosystem.Different Factors That Affect Soil FormationDifferent factors affect soil formation. Soil is made up of organic matter, inorganic matter and airOrganic matter makes up the most part of soil. Soil is affected by physical weathering, chemical weathering, biological weathering, and mechanical weathering.Physical Weathering: The process of erosion is a type of physical weathering that causes soil to be created and transported in water or wind. Another example is leaching where water carries dissolved materials into the ground which changes the soil composition from its original state.Chemical Weathering: Chemical changes in rocks can take place when rocks are exposed to rainwater or other liquids like acids and bases. When these liquids contact with rocks they can cause chemical reactions that dissolve minerals from the rock surface which alters the soil composition.Biological Weathering: Biological weathering is the breakdown of rocks and minerals by the process of biological action. This process occurs on global scales, but it is most prevalent in tropical rainforests.Biological weathering happens when organic material is broken down by bacteria, fungi, and insects. This breakdown of the rock creates new compounds that were not present before. These new compounds are often more soluble and therefore break down faster than the original ones did.Mechanical Weathering:Mechanical weathering is the process of surfaces being eroded by physical contact and movement between rock and other materials.Mechanical weathering can be broken down into four major processes:Abrasion, which refers to the mechanical removal of material from a surface,Attrition, which is the process in which two surfaces interact through rubbing or grinding away one another’s material,Frost wedging, which is where water seeps into cracks in the rock and freezes. As it expands it breaks off pieces of rocks through sheer force of pressure. And finally Salt crystallization where salt deposits form on a rock surface due to evaporation in dry climates or when water evaporates from humid air and leaves behind salt deposits.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel reply Featured image Select file Browse Add a Video to describe the problem better.
