Which of the following factors does not affect soil formation? a. precipitation b. time c. erosion d. none of the above

Option (a) is the correct answer.

Precipitation is defined as the formation of a solid in a liquid which is not soluble.

Therefore, presence of an insoluble solid substance does not affect soil formation.

Whereas when natural forces like wind, water etc which erode away rocks and soil are known as erosion. Also, time is a factor that also affects the soil formation.

For example, in rainy season due to heavy rain soil erosion occurs which affects the soil formation.
