How is soil formed? Explain each point thoroughly.
Dear Student,
Soil is formed by a natural process known as weathering of rocks, where large pieces of rocks are broken down into smaller pieces.
Weathering occurs by following three means:
(i) Physical weathering: It occurs because of change in climatic factors such as temperature, wind, rain water, ice and snow.
(ii) Chemical weathering: It occurs through chemical processes such as hydrolysis, hydration, oxidation and reduction. The primary end products of chemical weathering are silica, clay, inorganic salts and hydrated oxides.
(iii) Biological weathering: It is carried out by living organisms such as lichens and bryophytes.
Regards,
