Air pressure fills a vacumm of non existing air into a chamber kind of like a balloon when u put air in it creates pressure. Our atmosphere is also like a big balloon, i hope that answers ur question thanks for playin.

When you drive down a mountain what makes your ears experience those uncomfortable sensations?
Your ears pop on a mountain when there's a difference in air pressure between your inner ear and the air outside. The air in your inner ear exchanges pretty slowly. And since the air is much thinner at the top of the mountain than it is near the bottom, if you go down quickly enough (like by driving) the pressures can't equalize gradually. The higher pressure air at the bottom of the mountain presses on your eardrums until they "pop" and the pressure equalizes. That can hurt!
How does air cause a pressure against a car windscreen?
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.
Weight of air pressing down?
Air pressure.
Does air flow from areas of higher pressure to areas of lower pressure?
Air will flow from areas of high pressure to areas of low pressure. Pressure = force/area. So in this context, air pressure is the force the particles in that area exert on the space around them (let's imagine they're in a box). As air particles whizz around, they will collide with the edges of the box, so bouncing off and changing direction. This direction change involves a lot of acceleration (though speed may be the same, velocity (which is speed in a specific DIRECTION) will be very different. Physics tells us F=MA. Therefore, this acceleration will equate to a force on the outside world. This force will therefore be proportional to the number of particles in the area (more particles = more area). So, if an area of high pressure has lots of particles, there will be a spreading out of these particles to areas of low particles (diffusion, and energy's natural tendency to spread out). Alternatively, think of it as particles in the high pressure area pushing against the particles from the low area, and they're pushing force being greater, so they win! There you have a very long winded answer for why air moves from high pressure to low pressure!
What happens to air when there is an area of lower pressure nearby?
The thing that is low pressure is air. When a meteorologist says that there is an area of "Low Pressure" he is saying that there is a low air pressure in an area or, more exactly, that there is less air per cubic unit than there is in surrounding areas. So, if neutrally pressured air met with low pressured air the neutrally pressured or comparatively condensed air, a.k.a "high pressure" air would fall downward until it reached a state of equilibrium. And attaining equilibrium by both mixing with the surrounding air and falling to an altitude of similar air pressure.
Why did the smoke move first in an upward direction and then a downward direction?
positive air pressure then hit a negative air pressure.
is air pressure is low when the air presses down a lot?
no, it becomes higher when the air presses down
What is is the amount of air that presses on something?
pressure
When the layer of air that surrounds the Earth presses down this is ?
Air pressure
When the layer of the air that surrounds the earth presses down this is called?
air pressure
What is downward displacement of air?
Downward displacement of air happens when you fill the upper part of a pressure chamber with steam. This causes the denser air below to move downward.
The ratio of the weight of air to the area on which it presses is called?
Atmospheric pressure
What is air presses down on earth wwith force?
Air that presses on the earth with force is atmospheric pressure. It is caused by changing in temperature and the natural movement of air around the Earth.
Can you convert a downdraft to an updraft?
You must change the direction of the air flow, This is done by converting the downward pressure upward. You either need to use a forced air fan to change direction of the downdraft or to divert the air that normally flows downward into an upward motion by causing the downward air to be diverted into upward air chambers forcing the air upward. WindKat cowls has come up with a pretty good idea for solving this problem with chimneys. They say it is the most anti-downdraft cowl on the market. You can find them on the Web.
What is it called when air presses on us?
air has mass
In which direction is air pressure?
Air pressure is exerted in all directions.
When a mass of cold air presses on the surface of the earth is called what?
low pressure area
