Air is about 78% nitrogen pretty much everywhere on Earth.
The air pressure at the surface of the Earth is much higher (roughly 14.7 pounds per square inch) compared to the air pressure at 7 miles above Earth, which is much lower due to the thinner atmosphere at higher altitudes. The pressure decreases with increasing altitude, following the barometric formula.
yes earth is much different than space because space has no air or water.
78% of earth's atomospere is made up of water
the atmosphere of earth weighs approximately 5×1018 kg, 3/4 of which is within 11 miles of the earth's surface.
