Kids Encyclopedia Facts. Air pressure is a measure of the weight of air above us in the atmosphere. Air pressure can change from place to place, and this causes air to move, flowing from areas of high pressure toward areas of low pressure.
The pressure of the air molecules changes as you move upward from sea level into the atmosphere. The highest pressure is at sea level where the density of the air molecules is the greatest.
