The weight of the air
The distance between particles of a gas determines the pressure. The distance can be decreased and the pressure therefore increased by either increasing the amount of particles of gas in the container, or by reducing the size of the container.

I have a science test this week and was wondering what causes air pressure differences on our planet?
Earthquakes. Pressure in the Earth's core.
Higher pressure on the convex side (from the heart contracting) than the concave side causes them to open. When the pressure reverses (the heart relaxes) they close.
because you run them to hard and it causes wear and tear. Specialy when you drive alot at high rpms it causes metal to metal.
Sometimes inflammation putting pressure on nerves will do this or pressure may be put on the nerves as they pass between the vertebrae in the neck.
