It can move back and forth in any direction; it depends on the specific situation.
Vibration is to move or cause to move continuously and rapidly to and fro. It is used in massage.

yes it can move a piece of paper ;]
vibration
Sound is a vibration. Vibration dies out from the friction of making something (like air) move. The energy to move the air is gradually changed to heat from the friction.
Sound waves propagate differently based on their direction of vibration. Longitudinal waves vibrate parallel to the direction of wave propagation, causing particles to move back and forth in the same direction as the wave. Transverse waves, on the other hand, vibrate perpendicular to the direction of wave propagation, causing particles to move up and down or side to side.
Rocks on the side of a spring will move if there is a earthquake. When a earthquake happens it shakes everything.
The vibration of the techtonic plates. :)
vibration and a medium for it to move through
Air particles move back and forth in the direction of the vibration when they cause it. The energy from the vibrations is transferred through the air as sound waves.
To cause a vibration, an object needs to have energy applied to it in the form of a force or disturbance. This energy causes the object to move back and forth, creating a vibration.
Electromagnetic waves, such as light, are vibration particles that can move through a vacuum. These waves do not require a medium to propagate and travel through empty space at the speed of light.
