Gases are compressible. More pressure means they are compressed into a smaller volume. Liquids not so much. Water has about the same density in a column.
Oh so at the surface of the earth, because the pressure is greater so it is more compressed while higher up the pressure is less so the compression is smaller?

But then again now with only one formula, P=hpg now that h and p decrease so the pressure will decrease disproportionately?
