Geology - Earthquakes Basics

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

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

• rebound

• deformed

• larger

• small

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

• rebound

• deformed

• larger

• small

Most earthquakes happen at or near the following tectonic plate boundary. 

• Divergent Boundaries

• Convergent Boundaries

• Transform Boundaries

• All of the above

Which type of stress causes deformation that leads to earthquakes at converging plate boundaries?

• tension

• stretching

• shear stress

• compression
