Earthquakes

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.

Earthquakes are caused when:

• Pressure builds up along a fault line where 2 tectonic plates meet. 

• The release of this energy along the fault causes an earthquake.

• Both A and B

• Neither A nor B

Many fault lines are obvious at the surface. How can the epicenter of an earthquake be located miles away from the fault line?

• The epicenter is the place of greatest damage, and it can be miles from the site of the earthquake.

• The earthquake happened at a place where there is no fault, so the epicenter is not near a fault line.

• Some large earthquakes have more than one epicenter, and these epicenters can be far from the fault line.

• The fault line does not extend straight down from the surface, so the focus is not directly beneath the point where the fault reaches the surface.

Why do most earthquakes take place at tectonic plate boundaries?

• The rock in the interior of a tectonic plate is stronger, so it does not deform.

• Earthquakes take place where the motion of tectonic plates transfers energy to rock.

• Earthquakes can only occur at places where magma can reach the surface and transfer energy to rocks.

• Earthquakes take place when one plate moves over another plate, which happens only at plate boundaries.
