What happens if the atmospheric pressure drops?
The wind blow in towards the low.
What causes the magma inside a volcano to rise to award the surface?
The molten magma increases in pressure (like a pressure cooker at home) until it is forced towards the surface.
Could property of magma that cause it to be forced upward towards earth surface?
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
In the Northern Hemisphere what is the direction of surface wind circulation in a low-pressure system?
Counter clockwise and towards the center
Why does molten rock from the mantle come to the surface at the mid-ocean ridges?
Magma is less dense than surrounding rock, so it rises up. Since there is no path down, there is a pressure build-up which forces the magma out of the volcano .
Does the air increase or decrease towards the surface with a high pressure?
Air density and pressure increase nearer the surface
What happens if the atmospheric pressure drops?
The wind blow in towards the low.
What causes the magma inside a volcano to rise to award the surface?
The molten magma increases in pressure (like a pressure cooker at home) until it is forced towards the surface.
How does the pressure change as you go from the surface towards the center of the Earth's?
the pressure changes by how deep you are below see level because of gravity?
Does are come together or move apart in an area of surface low pressure?
Air always flows towards areas of low pressure - and away from high pressure.

Does air pressure increase with the altitude?
No, air pressure decreases with altitude. As you go farther towards earth's surface, the weight of the atmosphere presses down with increasing force.
What happens when people walk in zero gravity?
Unless there's someting else pulling them towards the surface - they bounce off.
When a barometer rises air pressure is?
increasing
Where is the low pressure service port in a 95 Dodge Stratus?
low pressure towards the evaporator ( towards the inside of car) and the high pressure is towards the condensor in front of the radiator
What happens to temperature and pressure as you move from the surface of the earth towards the center?
The pressure increases. I actually did this last summer. We were traveling from sea level to the mountains in North Carolina. I had a bag of potato chips in the car. When we left the beach (sea level) the bag was a little puffy. When we looked at the bag at the top of Mount Mitchell it was swollen up so tight as if you had put an air hose in it. That was because the air pressure at sea level is greater than it is at higher altitudes. The pressure in the bag stayed the same but the air pressure outside of the bag became less making the bag puff up. If you go down into the earth the pressure in the chip bag will stay the same but the outside pressure will be greater crushing the bag and if you go far enough down it will probably mash your chips. This may not be the best description but it works for me.
