Why is atmospheric pressure greater at sea?
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
What happens to pressure as the air rises in the troposphere?
Air pressure is simply the weight of the air above you. Air pressure falls with height because the higher you go up, the less air there is above you to weigh down on you.
You carry a barometer with you to the top of a very tall buildingyou notice that the barometer reading goes down as you ride up to the107th floorexplain what happened and why?
Barometer's measure air pressure and the Earth's air pressure at a certain place is due to the weight of the air above it. So the higher you go the air pressure drops because there is less air above you pushing down with its weight.
Why does a barometer have a higher reading at sea level then at the top of the mountain?
Air pressure on earth results from the earth's gravitational pull on the earth's atmosphere. In some sense, pressure results from the weight of the air above the point at which one measures pressure. At higher altitudes, there is less air above, resulting in less weight, which translates into 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.
What is air pruessure?
The weight of air above us in the atmosphere
What is an air column?
the weight of a column of air above you that puts pressure on you
What is the measure of the weight of air above us called?
air pressure
What is the changes in air pressure caused by?
The changes are caused by the weight of air above it.
What is The force on a given area by the weight of air above it?
Downforce
Why does pressure drop as you travel upward from earth surface?
Air pressure is caused by the weight of the atmosphere above an object. When one goes higher, there is less air above and so the pressure drops.
Does air pressure decrease with increasing altitudes?
No, air pressure decreases with increasing elevation. This is because air pressure is due to the weight of the column of air above where you are. The higher you go, the less air there is above you, so the less the weight of that column of air and the lower the air pressure.
The measure of the weight of the air above us is called?
Atmospheric pressure.
What force on an object is caused by the weight of the air above the object?
gravity
What is the force put on a given area by the weight of air above it is?
Downforce
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.
Is air pressure greater when your higher up or lower?
Air pressure is caused by the weight of all the air stacked up above you. The higher you go, the less air there is above you, so the pressure is lower.
