How does atmospheric pressure change with elevation?

    Atmospheric pressure gets lower at higher elevations.  Think of all the particles in the air that are being pulled down by gravity.  The higher you go, the fewer and fewer particles there are which means there is less weight being pushed down on you and in turn less pressure.  In contrast, when going underwater, there are more and more water particles pushing down on you making the pressure much higher at deep parts of the sea.
