On earth it is responsible for air pressure. There are about 15 pounds of air above every square inch of the earth's surface. Or in other words, the volume of a column of air on Earth about a hundred miles high and a square inch in area weighs 15 pounds.

How can you calculat the specific gravity of air?
You could measure the weight of a recipient with air, and compare it to one without air (with a vacuum instead).
What is weight of 1 cubic meter of air?
At a temperature of 20 °C and a pressure of 101.325 kPa (standard pressure), dry air has a density of 1.2041 kg/m3.So the weight of 1 cubic meter of air under those conditions is 1.2041 kg.
How many liters of air is required to float X amount of pounds on water?
If you ignore the small weight of air relative to the weight of water, then one litre of airSUBMERGED in water provides a buoyant force equal to the weight of one litre of water,which is about 9.8 newtons or 2.2 pounds.
Is this statement true or false Air can cause friction?
true
How much does a 10 pound brick weigh underwater?
That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
What is the cause of air pressure?
it is the weight of the air that masses over you.
Air conditioning on can cause weight gain?
no it can make you gain weight!
How does pressure cause air to move?
Pressure cause air to move because all the weight pushes up or down and causes it to go the opposite direction.
Does swallowing air make you gain weight over time?
Swallowing air doesn't make you gain weight, but it does cause bloating. Bloating can make you look like you have gained a little bit of weight, until it stops.
What is the best cause of atmospheric pressure?
Gravity. Atmospheric pressure is the weight of a column of air. Of course, the temperature of that air changes it's density and therefore it's weight (i.e. pressure)
How does gravity cause air pressure?
Gravity causes air pressure by pulling air molecules towards the Earth's surface. The weight of the air above creates pressure on the air below it. The higher you go, the lesser the air pressure due to less weight above pushing down.
Air pressure is affected by temperature.?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
On a sensitive balance weigh an empty flat thin plastic bag Then weigh the bag filled with air Will the readings differ Why?
The readings will differ because the weight of the air inside the bag is being added to the weight of the bag itself. This additional weight from the air will cause the total weight of the bag filled with air to be greater than the weight of the empty bag.
A person feeling weight of air feels?
The weight of air is known as atmospheric pressure. A person may not physically feel the weight of air, but changes in atmospheric pressure can sometimes be felt in the ears or head, especially during changes in altitude like going up a mountain. This can cause discomfort or even pain in some individuals.
Does air have weight?
Anything with mass has weight; air has mass, therefore it has weight.
Give examples from daily life that air has weight?
air has weight
What is cause of atmospheric pressure?
Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of the air. Pg. 126 Conceptual Physical Science 4th Edition.
