true
Yes it's true, but that doesn't last very long. It creates a compression of the molecules during exactly half of each vibe, and during the other half, it leans the other way, and the molecules spread out in what's called a "rarefaction" ... a region of lower-than-normal pressure. This 'train' of compressions and rarefactions is what travels through the air, away from the vibrating object, and it's what some people often call a "sound wave".
sound
Compression, which is the "squeezing" together of molecules, and rarefaction, which is the expansion of the "squeezed" molecules back toward their original position, is the oscillatory behavior that causes sound waves. Individually, they are not types of sound waves, because for any wave you need both a disrupting force and a restoring force oscillating between each other.
compression or expansion of an elastic material causes elasticity.

a compression force would cause a normal fault. i rember by the name compress "press" together

That phenomenon is known as resonance.

You think probable to compression.
The molecules of any substance are attracted together. Heat causes the molecules of a solid to separate from each other, making the solid become a liquid.
