The shaking of Earth's crust caused by a release of energy

What is an earthquake?

100

Force that acts on rocks to change its shape or volume

What is stress?

100

Folds in rock are caused by this type of stress.

What is compression? 

100

The fastest type of seismic waves.

What are P-waves?

100

Tension is the stress found at this boundary.

What is divergent boundary? 
200

The movement of these causes earthquakes

200

Stress that thins rocks

What is tension?
200

A fold in rock that bends upward into an arch

200

Seismic waves that move from side to side or up and down.
