Q: The Beaufort scale is used to measure:
  • A. Atmospheric pressure
  • B. Altitudes of mountains
  • C. Wind velocity
  • D. Intensity of earthquakes
Correct Answer: Option C - Beaufort scale is an empirical scale. By which the wind velocity is measured. This scale ranges from 0 to 12. Zero is display silent air and 12 is display storms. It was discovered in 1805 Francis Beaufort.
