1.     Which statement is not true:

• Ground movement occurs when Earth layers move suddenly and release energy.

• The release of energy sends seismic waves out from the focus point of the Earth quake.

• Epicenter is the spot directly above the focus of the Earth’s surface.

• Earthquakes only affect a small area when one occurs.
