Earthquakes

Front

Which statement is not true about earthquakes?

• 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 earthquake.
• Epicenter is the spot directly above the focus of the Earth’s surface.
• Earthquakes only affect a small area when one occurs.

Back

Earthquakes only affect a small area when one occurs.

Front

What causes earthquakes?

Back

Pressure builds up along a fault line where 2 tectonic plates meet and the release of this energy along the fault.

Front

Rock becomes _________ and changes shape of the ground along a fault due to the stress.

Back

deformed

Front

After a sudden snap in the earthquake, the rock returns back to its original shape.

Back

rebound

Use the diagram to answer #12 Options: Epicenter, Wave Fronts, Fault, Focus

Back

Focus

Front

Where do most earthquakes happen in relation to tectonic plate boundaries?

Back

All of the above (Divergent, Convergent, Transform Boundaries)

Front

How can the epicenter of an earthquake be located miles away from the fault line?

Back

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.

Back

Epicenter

Front

Why do most earthquakes take place at tectonic plate boundaries?

Back

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

Front

Which type of stress causes deformation that leads to earthquakes at converging plate boundaries? Options: tension, stretching, shear stress, compression

Back

compression
