The relief features, parent material, climate, vegetation, and other life-forms, as well as time apart from human activities, are the major factors responsible for the formation of soil. By continuing to use our website, you agree to our. Temperature and rainfall are two main climatic factors responsible for soil formation. Topography (or relief) is also rather passive Factors affecting Soil Formation, mainly modifying the climatic influences of temperature and precipitation. Soil development is facilitated by the downward percolation of water. 2. Everything takes a … Soil is formed from weathering of rocks and minerals. Both mechanical and chemical weathering play an important role in soil formation. Here, we are giving a brief note on the major factors which are responsible for the formation of the Soil. (i) On the basis of origin – biotic and abiotic. (ii) Various forces of nature such as change in temperature, actions of running water, wind and glaciers, activities of decomposers, etc. Soil formation processes are continuous. Parent Material: The material for soil formation is mainly derived from the rocks and is termed as … The soil is a living system. The geological components are mixed with organic materials to form soil. High temperatures and rainfall increase the degree of weathering and therefore the extent of soil development. Gully erosion is also responsible for the formation of ravines. For example- Black soil-derives its colour from lava rock. State the major factor that decides the structure of soil. Soil formation is a process strongly driven by the boundary conditions for the soil system. As water seeps downwards, it breaks down material. The material in which soils form is called “parent material.” In the lower part of the soils, these … The process responsible for soil formation is called _____. For Example- Areas with little rainfall and a high rate of evaporation led to the accumulation of salts in the soil. Role of temperature: It also plays an important role because fluctuations in temperature causes shrinking and swelling, frost action, and general weathering in soil. 1. (250 words). Zigya App. The soils of India are as diverse as itself. The soils underlying tropical rain forests tend to be nutrient-poor because of intensive leaching due to heavy rains. Time is perhaps the most important factor when it comes to soil formation. Time - Time is also a component for the other factors to interact with the soil. Recently deposited material, such as the deposition from a flood, exhibits no features from soil … This question hasn't been answered yet Ask an expert. There are various forces of nature which act as the factors that are responsible for the formation of soil. Younger soils have some characteristics from their parent material, but as they age, the addition of organic matter, exposure to moisture, and other environmental factors may change its features. Materials may have moved many miles or only a few feet. Answer: Two main climatic factors responsible for soil formation are Temperature and Rainfall, wherein rainfall influences the rate of weathering and humus formation. Wind can lift the valuable top soil from one area and deposits in another area. Please read the following text chapter, which is available through Library Resources: Brady, N. C., and R. R.
