Question

Which of the following is the most important factor in soil formation?

• A. Relief
• B. Climate
• C. Natural vegetation
• D. Rock cover

Answer 1

The correct option is B Climate

Climate:

This is probably the most important factor that can shape the formation of soils. Two important climatic components, temperature and precipitation are key. They determine how quickly weathering will be, and what kind of organic materials may be available on and inside of the soils. Moisture determines the chemical and biological reactions that will occur as the soils are formed. Warmer climate with more rainfall means more vegetative cover and more animal action. It also means more runoff, more percolation and more water erosion. They all help to determine the kind of soils in an area.
