Q: The--------- soil transported by the gravitational forces.
  • A. alluvial soil
  • B. colluvial soil
  • C. loess
  • D. till
Correct Answer: Option B - Colluvial soil are formed due to gravity forces. In mountains and hills, on steep slopes soil creeps down under gravity force due to variation of moisture content (hence loosening of soil). Such soils are deposited in the lower part of the mountains i.e. valley. And the soil transported by the water is are Alluvial, Marine and Lacustrine soil.
