What are the 5 main factors that affect soil formation?
The whole soil, from the surface to its lowest depths, develops naturally as a result of these five factors. The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time.

What are the four processes of soil formation?
Four basic processes occur in soils— additions, losses, transformations (changes), and translocation (movement) .
Which factor does not help in the formation of the soil?
Soil texture is not a factor which is responsible for the soil formation. Parent material (minerals and nutrients), Time, Climate, Relief and Organisms are the factors which are responsible for the soil formation.
What are the factors that influence soil formation Class 7?
There are five groups of factors responsible for the kind, rate and extent of soil development. They are: Climate, organisms, parent material, topography and time . Soil from one place is different from another because of the differences in the influence of these factors.
