Answer» Importance of soilAs one it the most important components of the sustainability of an ecosystem, soil we said be of great importance when it comes to the growth of vegetation.Factors Responsible for the Formation of Soil are1. Parent Material: Deposited by streams or derived from in-situ weathering, these soil come with many properties like the mineral composition, the color, the particle size, and the chemical elements.2. Climate: The rate of weathering of the parent rock is affected by varied climate. Hence it is said to be an important factor in determining soil formation.3. Role of temperature: Any change in temperature can cause shrinking and swelling, frost action and general weathering in soils. Hence, temparature is said to play a vital role in soil formation. Soils\xa0provide plants with essential minerals and nutrients.\xa0Soils\xa0provide air for gaseous exchange between roots and atmosphere.\xa0Soils\xa0protect plants from erosion and other destructive physical, biological and chemical activity.\xa0Soils\xa0hold water (moisture) and maintain adequate aeration.\xa0Soils\xa0form from the interplay of five main\xa0factors\xa0namely Parent material, Time, Climate, Relief and Organisms. Parent material: This refers to the mineral material or organic material from which the\xa0soil\xa0is\xa0formed. ... This is probably the most important\xa0factor\xa0that can shape the\xa0formation of soils. |
