Air pressure is the weight of air pressing down on the earth it is measured by a barometer what kind of weather does high pressure usually bring?
humidity
Why is air pressure greatest at the Earth's surface?
Because as you get closer to the surface of the earth, the more air that is on top of you. At the top of the atmosphere, there is no air, and everything is a vacuum, where you have no weight. When you get close to the earth, the weight of the air builds until it when you're at the very lowest point of the earths surface, all the air in the atmosphere above you is pressing down.
Which of these is an area of cool air pressing down on the earth?
A high pressure area or "anticyclone".
What is the weight of the air pushing down on the earth?
It is called air pressure
Why does air exert pressure?
Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
Is the weight of the air pressing down on earth?
Air pressure

The weight of the earth's atmosphere pressing in all directions?
Air preasure

Why is air dense at sea level?
The air has the weight of all the air above it pressing down on it. this compresses the air increasing its density. So air at sea level is more dense than air on the top of the mountain, since the air on the mountain top has less air above it pressing down.
Why does th humanbody notcollapseunder the weight of the air pressing down on it?
Due to blood pressure maintained by the heart.
How much weight of air is pressing down on 1 square inch of the top of your head?
roughly 14.6 pounds
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 does air pressure becomes lower as water molecules are added to the air?
Air pressure is the weight of the air at a specific location. On the surface of the earth, we have the entire weight of the atmosphere pressing on us in the form of air molecules like O2, N2, and CO2. As we go higher and higher into the atmosphere, there are fewer molecules and so there is less weight pressing against us.
What is a barometer used to measure?
the weight of the air pressing down on the earths surface is known as air pressure.this pressure is measured using a barometer
