Question 15

State two factors which affect the atmospheric pressure as we go up.

Answer

The atmospheric pressure decreases as we go up because —

  1. Decrease in height of air column which causes a linear decrease in the atmospheric pressure.
  2. Decrease in density of air which causes a non-linear decrease in atmospheric pressure.
