Which of the following is true?

atmospheric pressure increases exponentially with height

atmospheric pressure increases linearly with height.

Atmospheric pressure increases exponentially with height, diagrams is given sn reference.

Explanation:

As the pressure is inversely proportional to altitude, as the molecules of air are pulled down under the action of gravity and hence constantly in motion near the altitude if 30 kilometers. Most of the atmospheric activity takes place in troposphere and inversion starts from the tropopause as the air becomes light and hence decrease in density and the above stratosphere there is again a sharp inversion as the air began to cool to -85 degrees till it reaches the mesosphere and after which it starts to rise in thermosphere to 1500 degrees. Thus there is a zig-zag or s-shaped layer of the atmosphere found above the horizon of the earth.
