Consider the following statements regarding soil-forming factors and choose the correct option from the alternatives given below. Assertion (A): Tropical soils with higher temperatures show deeper profiles Reason (R): Chemical activity within the soil is increased in higher temperatures Correct Answer Both A and R are true but R is the correct explanation of A

The correct answer is option 1, i.e Both A and R are true but R is the correct explanation of A.

  • Temperature is one of the important factor soil forming process.
  • It acts in two ways — increasing or reducing chemical and biological activity.
  • Chemical activity is increased in higher temperatures, reduced in cooler temperatures (with an exception of carbonation) and stops in freezing conditions.
  • That is why, tropical soils with higher temperatures show deeper profiles and in the frozen tundra regions soils contain largely mechanically broken materials.
  • Hence, both statements are individually correct and R is the correct explanation of A.
