As altitude increases, air pressure decreases. Gravity causes the atmosphere to become heavier the closer you are to the ground. The atmosphere may seem weightless but all the air molecules add up to a tremendous amount of mass. If you think of the atmosphere like blankets, the more blankets you have piled on you the heavier they become, thus pressing down on your body more and more. This is the same in the atmosphere, where the higher the altitude, the less overlying atmosphere, the less pressure on air molecules. At higher altitudes the air molecules have more freedom to move around.

As elevation decreases, pressure increases. Just think of what happens when you swim to the bottom of a pool....your ears hurt and pop the further you go down. The same thing happens when you drive down a mountain.

The pressure gets higher as altitude decreases, because the air below has to support the weight of the air above it, becoming compressed.
