Which of the following terms is not applicable to the weathering process ?

  • A.Regolith
  • B.Saprolite
  • C.Chelation
  • D.Slump

Answer: D

The term not applicable to weathering is slump.

A slump is a form of mass movement: a block of earth or rock slides down along a curved, spoon-shaped surface and rotates backwards as it moves. It is a transport process acting on material that weathering has already prepared.

The other three belong to weathering. Regolith is the layer of loose weathered material over bedrock, saprolite is rock chemically weathered in place that keeps its original structure, and chelation is a chemical weathering process in which organic compounds bind and remove metal ions from minerals.
