Give The meaning of:
Tension
Compression
Shearing
Tension-The stress force that pulls on the crust and thin rock in the middle.

P Waves- Are seismic waves that compress and expand the ground like an accordion.
S Waves – Are Seismic Waves that can vibrate from side to side or up or down.
Surface Wave- When P and S Waves reach the surface; some of them become surface waves.
