If the air pressure gets higher does it mean that there are more molecules pressing down?
Rosalina2427
quite right. Air pressure is the result of millions of air molecules impinging on the surface per unit area. The higher the air pressure, the higher the number of strikes from air molecules.

What are Molecules closer to the surface are more densely packed than those higher in the atmosphere because of the mass of gases pressing down from higher in the atmosphere?
Im pretty sure its atmospheric pressure
Does pressure increase or decrease with altitude?
Because as you climb higher there is less air above you pressing down on you with its weight.
Why is the air pressure lower at higher altitude?
Same reason water pressure is higher the deeper you go. There's more stuff above, pressing down. Air has density and weight too.
What is a low-pressure system and what is a high-pressure system?
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
What happens when the air molecules that are constantly pressing down on us due to gravity?
it squeeses use a bit if it is alot it will crush use

What happens to the air pressure as you go higher?
Air pressure decreases as you move higher in the atmosphere. Air, just like any form of matter has mass, and when affected by earth's gravity, weight. The weight of air is pushing down on you with a force of 1 atmosphere at sea level. As you increase elevation the air pressure is reduced because there is less air to push down on you. Just like air, water pressure increases as you increase your depth in it, or any fluid.
Why is the force exerted on the same amount of area on top of the mountain less than the force exerted at sea level?
Although you didn't mention air pressure, that seems to be what you are asking about. Air exerts pressure because air has weight, and we have a very thick atmosphere (which extends upward for about 200 miles) pressing down on us. But at higher altitudes, such as a mountain top, there is less air pressing down, since only the part of the atmosphere that is higher than where you are, is pressing down on you.
Is the weight of the air pressing down on the Earth?
Air pressure
What is the name of the air pressing down on us?
Air pressure
Is the weight of the air pressing down on earth?
Air pressure
Why is there pressure in the ocean?
There is pressure in all water because of the weight of the water above it pressing down
What happens to the air pressures as altitude increases?
As altitude increases, air pressure decreases. Gravity causes the atmosphere to become heavier the closer you are to the ground. The atmosphere may seem weightless but all the air molecules add up to a tremendous amount of mass. If you think of the atmosphere like blankets, the more blankets you have piled on you the heavier they become, thus pressing down on your body more and more. This is the same in the atmosphere, where the higher the altitude, the less overlying atmosphere, the less pressure on air molecules. At higher altitudes the air molecules have more freedom to move around.
Is air mass and air pressure the same thing?
No. An air mass is a section of the atmosphere with certain characteristics of temperature and humidity that distinguish it from nearby air masses. Air pressure is, in simple terms, how much the air is pressing down on the surface.
