The air that surrounds our Earth makes up the atmosphere. Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%.

The atmosphere is bound to Earth by gravity.
Dry air contains (by volume) 78% nitrogen, 20.95% oxygen, .9% argon, 0.04% carbon dioxide, and other gasses in small amounts. Water vapor can vary, displacing these, and is typically 1% but can be several percent.
Also:
The pressure at the surface of the Earth is 14.7 pounds per square inch or one atmosphere or one pascal or 760 millimeters of Mercury.
That pressure is the weight per unit area of all the air that is being pulled down by the attraction of the Earth's gravity.
Very light gasses, like hydrogen and helium, do escape from the atmosphere, but the remainder are pretty stable.
Sometimes a molecule the Earth's atmosphere is hit by a cosmic ray or a particle from the solar wind from the Sun and this can cause the molecule to move off into space. Mostly the Earth's magnetic field prevents charged particles in the solar wind from having great effect on the atmosphere, but that is not 100% protection.

What is the air that surrounds the earth called?
It is called the Atmosphere.
The measure of the force with air molecules push on a surface is called?
The measure of the force due to air pressing on a surface is called the force.If you divide that by the area of the surface, then you have the pressure.
Which process produces rising air due to unequal heating of earths surface?
Frontal wedging
How do convection uplift occurs?
A parcel of air is uplifted when it initially gains heat from the surface causing convective uplift.When the air is warmed by the surface it will expand and become less dense relative to air that surrounds it. - See more at: http://www.chacha.com/question/can-you-briefly-describe-how-convective-uplift-occurs#sthash.JinBHwPh.dpuf
What are facts about air resistance?
What type of friction is air resistance?fluid friction. Air resistance is fluid friction. Air resistance occurs between the surface of a falling object and the air that surrounds it. Rolling friction occurs when a rounded surface moves over a solid and sliding friction occurs when a solid moves over another solid. Static friction occurs when a solid touches another solid but there is no movement.What two factors affect air resistance?size and shape. Size and shape are the two factors that affect air resistance. Air resistance works with surface area, so the more surface area, the more air resistance. Think about when you drop two pieces of paper: one crumpled and one flat. The crumpled one falls faster because there is less air resistance acting on the paper.
