chapter 12 Sci. test

Elastic Rebound The sudden return of elastically deformed rock to its un-deformed shape.
Focus The location within the Earth along a fault at which the first motion of an earthquake occurs.
Epicenter The point on Earth's surface directly above an earthquake's starting point, or focus.
Seismic Waves Energy released in the form of vibrations as rocks along a fault ship into place.
Fault Zone A region of numerous, closely spaced faults.
How does stress build up along a fault and get released? Although the rocks may be under stress, friction prevents them from moving past each other, Parts of a fault remain locked until the stress becomes so great that the rocks suddenly slip past each other. This slipping causes trembling and vibrations.
