Air evaporates
as the altitude increases density of air decreases.This makes it harder to breath.
Air becomes less dense as you climb the mountain.
As you climb the mountain, the air pressure decreases. The temperature also drops.
As you climb a mountain the air gets colder.
air pressure on the high mountain is because air flow is fast or velocity of air is more on the high mountain
less
The atmosphere is full of layers and when you are at ground level, you have a maximum amount of air above you, but when you climb the mountain, the amount of air decreases and thus the pressure Hope that was helpful!
Because there is more air (which has weight) above you if you are around sea level. If you fly up, or climb a mountain, there is less air above you, therefore less air pressure.
The air is thinner
i think a valley does because when you climb a mountain the air pressure decreases the higher you go.
it decreases
all the air pressure goes down, so as you get higher up, there is less in the air
