Question

With an example explain how the pressure decreases and increases as the height from the ground increases and decreases respectively.

Answer 1

Explanation:

Air molecules colliding with a surface cause atmospheric pressure. ... Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases: the number of air molecules decreases.

Answer 2

The pressure exerted by a liquid depends on the height of the liquid column.

We know that pressure can be also written as P=ρgh

Where h is height and ρ is density.

Now as the height increases , pressure will also increase .
