How does barometric pressure vary with altitude?
pressure is a physical unit that measures what we may call the density of force i.e. trhe amount of force exerted on a certain area , the atmosphiric pressure is the force exerted by the air mass on a certain area , clearly more air means more mass , thus , when we go down the air above us increases , and when we go down the amount of air decreases.
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.
Why does the air in the atmosphere press on us?
It's due to air pressure.
Why the pressure vareis from moutanins to land?
High up on the mountains, there is less air above us. It is the air that causes the pressure.
What is The weight of air measured in units of force per area is called?
The measure of the weight of the air above us is called air pressure. Air pressure varies depending on your location.

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.
What produces air pressure at the surface of the earth?
Air pressure is the force exerted by the gases in the atmosphere as Earth's gravity pulls on it. The atmosphere can be thought of as a 'sea' of gas surrounding the planet. Air pushes against us from all directions as the weight of air above compresses the air below (this is why altitude affects air pressure.)

What causes pressure exerted by a fluid?
7th grade omg i rememer this!i hated it i wished my teach didnt teach us this
What is it called when air presses on us?
air has mass
Why does the air pressure change the altitude in the atmosphere?
As the amount of air above us decreases...the air pressure decreases.
What is the name of the air pressing down on us?
Air pressure
In the US what scale is used to measure air pressure?
Barometer. Air Pressure is measured in pounds per square inch. A Baromerter measure air pressure.
What is the measure of the weight of air above us called?
air pressure
Why does the air in the atmosphere press on us?
It's due to air pressure.
If the weather forecaster tells you that the pressure is falling what is the air density doing?
They tell you exactly the pressure is falling when the density of the air around us gets less, this means that air from other area's will be moving toward us to fill the air pressure up, air always moves from a high pressure area to a lower pressure area
