which factor leads to soil formation among following (a) freezing (b) heating (b) wetting (d) cooling
Answers
Explanation:
Soil and soil formation can be considered from many standpoints, including from the study of soil science as a field in its own right. However, soil is most important in ecological function as the basis for the growth of terrestrial plants, including supplying nutrients, water, temperature moderation, and support. Soil also provides important functions as a pool of carbon that can either act as a source or sink for atmospheric carbon dioxide, a habitat for soil organisms, and a filtration system for surface and ground water. Soil has often been considered a nonrenewable resource like coal or oil, and not a renewable resource such as agriculture or forests. However, in many cases, soil is a slowly renewable resource, and degraded soil can sometimes be restored to serve much of its original ecological function, though restoration may take decades or longer. A primary understanding of soil is achieved through the study of the soil profile, interactions of soil material with organisms, and the movement of water through the soil profile by leaching. An essential function of soil is the breakdown of organic material to form soil humus and release nutrients that can be utilized by soil organisms and growing plants. Soil is also an important reservoir of the Earth’s biodiversity, containing higher species and functional biodiversity than any other portion of terrestrial ecosystems.
wetting is helping unfortunately soil formation
