explain three factors responsible for soil formation (plz explain full three factors)
Answers
Answer:
AFFORESTATION
WEATHERING
HUMUS
Explanation:
. 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
Climate: It is one of the important factors in the formation of soil because it affects the rate of weathering of the parent rock.
Role of precipitation: The 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.
