Contours that are close together indicate

  • A.a flat plateau surface
  • B.a change in the datum
  • C.a steep slope
  • D.a gentle slope

Answer: C

Close spacing means a large height change over a short ground distance, which is steepness. Widely spaced contours mean the same height change is spread over much more ground, so the slope there is gentle. Reading spacing as gradient is the first skill a map user acquires.
