It is due to air, the higher you go, the less air is there, so the atmospheric pressure is decreased.

because air was weight. The lower you go the more pressure there is. It is the same with water. If you have ever attempted to swim under water the pressure increases very fast as you go deeper. The air is light and its pressure increases more slowly than water.
Next time you have a helium balloon in a car, notice that when the car goes forward the balloon also goes forward even faster. When you step on the break the balloon will go backwards toward the rear. This is because the air has weight and it sloshes around in the car. Since the balloon is lighter than air when the car's break is applied the air in the car sloshes forward and it is heavier than the balloon so the balloon goes in the other direction.

while usmcsting answer is part of the answer it doesn't answer why. Just as pressure increases
every 33 ft you descend in water it also decreases at the same rate as you ascend. for example; an airliner with passengers could not fly at 36,000 ft without the cabin being pressurized. Case in point the golfer that died a few years ago due to lose of pressure in the cabin. without the weight of the atmosphere pressing down on us we don't get enough o2.

the main community and least complicated to appreciate occasion concerns the sea breeze that comes up maximum afternoons on the coastline. What happens is that the land heats on a sunny day and as you realize heat air rises. because of the fact the temperature of the water is extra consistent the air over the water (severe tension) rushes in to fill the void (low tension). The opposite many times happens at night because of the fact the land cools. the version in atmospheric tension is led to via the thermal transformations the sunlight ingredients. the section on the equator is yet another occasion vs. the polar areas. wish that facilitates!

You say it-pressure. THe force of attoms from almost none in upper space to where you stand. Just add up the weight. If it was just gravity-you would still have to know which graitional force it is.
