why does atmospheric pressure decrease with height?

Answer 1

Well, there is less atmosphere pushing DOWN on you or your meter as you gain altitude. Now, go do the REST of your homework on your own!

Answer 2

The pressure of atmosphere at any point is the pressure due to the weight of the air above that point.As the height is increased,the column of air resting between this height and surface cannot be taken into consideration for the purpose of exerting weight.Therefore, the net pressure exerted at this level is due to the weight of the air column of air resting on unit area at the level considered.This shows , the atmospheric pressure decreases with height.

Answer 3

The pressure decreases because there's less of the atmosphere pushing down on you. As you go lower, the pressure increases because there is more atmosphere pushing down on you.

Answer 4

Pressure decreases with height because gravity pulls air particles down towards the Earth's surface. Less particles in a larger volume (the whole sky) causes a decrease in pressure.

Answer 5

Pressure is mass per unit area.
As height increases, the mass above is decreasing and therefore exerting a lower atmospheric pressure.

Answer 6

You can think of atmospheric pressure as a 'stack' of air on top of you. The more air that's above you, the greater the pressure it exerts on you.

When you travel a few miles up, there is much less air above you, so there's much less pressure. Eventually, you're above all the air, and there is zero pressure.

It's the same reason why pressure increases as you go further underwater. The more stuff there is on top of you, the greater the pressure.

Answer 7

because the density of air decreases as wego up.OR the weight of the column of air decreases as we go up in the atmosphere.
