Explain how soil composition is affected by environmental factors.
Answers
Answer: Soils form from the interplay of five main factors namely parent material, time, climate, relief, and organisms. Parent material: soils will carry the parent material such as color, texture, structure, mineral composition and so on.
The soil composition is affected by environmental factors by the following ways -
• Climate : The climate plays a great role in the formation process of the soil and that's why the soil composition is directly affected by the climate of a particular region.
Example : The desert soil has less amount of soil moisture than the plane land's soil,due to the less amount of rainfall in the desert regions.
• Organic matters : The basic formation of the soil is highly dependent on various organic matters and microorganisms.
Example : There are many nitrogen fixation bacteria which increases the nitrogenous compounds in the soil.
• River deposition : One of the key factors of the soil formation is the deposition work of the soil.
Example : The the main constituents of the soil are mostly come from the deposition work of the river and that's it's a key factor which decides the composition of soil of a particular region.
