OIt decreases.
OIt stays the same.

Answer 1

As altitude increases, air pressure decreases.

Step-by-step explanation:

As altitude increases, air pressure decreases.

This is because as you move higher in the atmosphere, the amount of air above you decreases. With less air above you, there is less weight or force pushing down on you, resulting in lower air pressure at higher altitudes.

For example, at sea level, the air pressure is higher because there is more air above us. But as we go up a mountain or fly in an airplane, the air pressure gradually decreases.
