  1. A steep valley by river erosion

  2. A valley with gentle slopes

  3. A valley formed by the sinking of ground between two almost parallel faults

  4. A valley carved by aeolian erosion

Show answer
Correct Option: C
Explanation:
  • When two plates of earth's crust move apart from each other, a long narrow depression is formed due to the sinking of ground which is called a rift valley eg. east African rift valley. Hence option C is the right answer.
  • The rift valley is not formed due to river or aeolian(wind) action. Also, the slope in the rift valley is almost vertical thus very steep hence other options are incorrect.
