The intensity of rain is expressed in A. cm/minute B. cm/hour C. cm/day D. None of these

cm/minute
cm/hour
cm/day
None of these

The correct answer is: B. cm/hour

The intensity of rain is the amount of rain that falls in a given area in a given amount of time. It is usually measured in millimeters per hour (mm/h) or centimeters per hour (cm/h).

  • Option A: cm/minute is not a common unit for measuring the intensity of rain.
  • Option C: cm/day is a common unit for measuring the amount of rain that falls in a given area in a given day. However, it is not a good unit for measuring the intensity of rain, because it does not take into account the time over which the rain falls.
  • Option D: None of these is the correct answer.
