A fault is classified by the ______________.

• number of earthquakes that occur along it

• type of plate boundary it occurs along

• directions in which rocks move along it

• distance the rocks on either side of the fault move

The stress that causes strike-slip faults _____________.

• pushed rock horizontally (back and forth)

• pushes rock vertically (up and/or down)

• pulls rock apart

• pushes rock together

Why do most earthquakes occur at tectonic plate boundaries?

• There is little or no movement of rock in these areas.

• Large amounts of stress build up as plates move.

• Very little stress builds up along tectonic plate boundaries.

• Most faults occur in the middle of tectonic plates.
