Introduction to Earthquakes

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

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

• Divergent Boundaries

• Convergent Boundaries

• Transform Boundaries

• All of the above

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.

How does distance from the epicenter of an earthquake change the earthquake’s effects?

• The strongest effects are at the epicenter.

• The strongest effects are felt furthest from the epicenter.

• The strongest effects are felt in a line extending north and south from the epicenter.

• The strongest effects are in a ring surrounding the epicenter with a radius of several miles.

What was the cause of this tsunami?

• an earthquake beneath the ocean

• the impact of a large meteorite in the ocean

• a sudden violent windstorm above the ocean water

• a typhoon moving from the Indian Ocean toward India
