Solution
The correct option is C About 500 years
It may take hundreds to thousands of years for an inch of topsoil to form. It will take longer in colder and drier regions than in warmer and wetter regions. This is due to the soil-forming processes such as translocation and transformation being slower in cold and dry areas. Essentially, chemical reactions (weathering) occur faster as temperature increases. Since soil formation also requires organisms and organisms require water, reactions (formation) occur faster if there is sufficient water present.
