Accelerated erosion chiefly occurs in ____________.

  • A.Mountains
  • B.Plains
  • C.Valleys
  • D.Plateaus

Answer: A

Accelerated erosion chiefly occurs in mountains.

The passage gives "accelerated erosion as in the mountain regions of the country" as one of the ways in which impoverishment of land shows itself. The plains are named for site quality decline and monoculture, and arid and semi-arid areas for salinization, not for accelerated erosion.
