A narrow gap in an uplifted range or topographic feature through which water flows :

  • A.Wind gap
  • B.Dry valley
  • C.Water gap
  • D.Col

Answer: C

A narrow gap through which water flows across a ridge is a water gap.

A water gap is cut by a river that maintains its course across a rising ridge (antecedent drainage) or that was superimposed from overlying rocks, so the river still flows through the notch it carved.

A wind gap is the same kind of notch from which the river has since been diverted, usually by river capture, so no water flows through it now. A dry valley is a valley without a permanent stream, and a col is a low pass or saddle between two peaks, not a gap carrying a river.
