Question

Explain any
three factors responsible
for soil formation?

Note: PL Answer Briefly​

Answer 1

Answer:

. Parent Material

: It is deposited by streams or derived from in-situ weathering. In this stage, soil inherits many properties like the mineral composition, the colour, the particle size and the chemical elements. For example- Black soil derived its colour from lava rock

2. Climate:

It is one of the important factors in the formation of soil because it affects the rate of weathering of the parent rock

variability in the precipitation modified the composition of the soil. For Example- Areas with little rainfall with high rate of evaporation led to the accumulation of salts in the soil. The soils underlying tropical rain forests tend to be nutrient-poor because of intensive leaching due to heavy rains.

4. Role of temperature: It is also play important role because fluctuations in temperature causes shrinking and swelling, frost action and general weathering in soils.
