Multiple choice

Which of the following is the correct reason for the absence of strong upward winds on the Earth's surface?

  1. Because the vertical pressure gradient force is much larger than that of the horizontal pressure gradient

  2. Because the vertical pressure gradient force is similar to that of the horizontal pressure gradient

  3. Because the vertical pressure gradient force is balanced by a nearly equal but opposite gravitational force

  4. Because the vertical gradient force is lesser than that of the horizontal pressure gradient

  5. Because there is no vertical gradient force in the lower atmosphere and the air remains heavy and follows the horizontal pressure gradient

C Correct answer
Explanation

This is the correct answer. The vertical pressure gradient force is much larger than that of the horizontal pressuregradient. But, it is generally balanced by a nearly equal, but opposite gravitational force. Hence, we do not experience strong upward winds.
