Question

why does atmosphere pressure it decrease as we go higher​

Answer 1

Explanation:

Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases: the number of air molecules decreases. the weight of the air decreases.

Answer 2

Explanation:

Air molecules colliding with a surface cause atmospheric pressure. Atmospheric pressure at sea level is about 101,000 Pa (101 kPa) but just 27,000 Pa (27 kPa) at the cruising altitude of a passenger plane.

The atmosphere is the layer of air around the Earth. Key features of the atmosphere:

• it is thin compared to the size of the Earth
• it becomes less dense as the altitude increases
