The air surrounding Earth is our atmosphere.
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 surrounding and bound to earth?
The air surrounding and bound to Earth is composed of a mixture of gases, primarily nitrogen (about 78%) and oxygen (about 21%). This mixture also includes small amounts of other gases, such as argon, carbon dioxide, and traces of water vapor. This unique blend of gases creates Earth's atmosphere, which is essential for supporting life on the planet.
What makes up close to one fourth of the air surrounding the earth?
Oxygen makes up 20.95% of the air surrounding Earth (that is almost 25%).
What gas makes up close to one quarter of the air surrounding earth?
Oxygen makes up close to one quarter of the air surrounding Earth.
What is the earth's blanket of air called?
The earth's blanket of air is called the atmosphere.
What is the push of air on the Earth called?
The push of air on the Earth is called atmospheric pressure. It is the force exerted by the weight of the air above a given point on Earth's surface.
