What is air pressure and how does it change with altitude?

• Air pressure is the force exerted by the wind on the earth's surface. It increases with increasing altitude.

• Air pressure is the force exerted on a surface by the weight of the air above the surface. It decreases with increasing altitude.

• Air pressure is the amount of oxygen in the atmosphere. It remains constant regardless of altitude.

• Air pressure is the temperature of the air. It fluctuates randomly with altitude.
