Question

explain with the help of a diagram how soil is formed

Answer 1






















The soil formation process depends upon the presence of new soil material which is either acquired by denudation or deposition. Denudation is the abrasion of present rock material by the action of ice, water or wind. Deposition is the accumulation of new materials that have been eroded from another place such as river gravels or blown gravel or the creation of new rocks due to volcanic action or the uplift of the ocean.

So, these two actions are responsible for availing new parent materials that begin the process of soil formation. Examples of new parent materials include rocks, loess, gravel, alluvium, scree, and sand. Soils then begin to form from these materials through the process of weathering together with other chemical and physical processes as outlined below.

Answer 2

Answer:

Soil is formed through the process of weathering. 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 pieces and eventually to soil.
