Atmospheric pressure decreases with an increase in altitude because:
Acceleration due to gravity increases with altitude.
Temperature increases with altitude.
Internal energy increases with altitude.
Interaction among air molecules decreases due to less quantity of air.
توضیح
As altitude rises, there is less air above a particular point, leading to a decrease in atmospheric pressure. Furthermore, the density of air diminishes with increased altitude, which also contributes to this phenomenon.
