___________________________________________________.
2. A fault where rock on one side of a fault slides downward and away from the opposite wall of rock is a
_____________________________________.
3. A ________________________________________ is a fault where rock on one side of a fault slides up and over rock
on the opposite side as plates move together.
4. The point inside Earth where energy is released as rocks crack and break is called the
______________________________________________________.
5. A fault where rocks on either side grind past each other with little upward or downward movement is a
________________________________________.
6. When rocks on Earth’s surface crack and break, they move along surfaces called
________________________________________.
7. Waves generated by an earthquake that travel through Earth are called
_____________________________________________________________.
8. The fastest-moving vibrations from an earthquake move in a back-and-forth motion in the same way the wave is
traveling and are called ________________________________________________________________.
9. The second-fastest moving vibrations move at right angles to the direction of wave travel and are called
________________________________________________________________.
10. The most damaging vibrations from an earthquake are called __________________________________________,
and they move in a backward, rolling and side-to-side motion.
11. The point on Earth’s crust directly above where the rock breaks is the _____________________________________.
12. A ___________________________________________________________________________ is an instrument that
measures the vibrations of an earthquake.
CONCEPTS –Answer in complete sentences where necessary.

19. The order in which seismic waves reach an earthquake recording station are
________________________________________________ waves, __________________________________________
waves, and then _________________________________________________ waves called
__________________________ and _____________________________ waves.
20. The thickness of Earth’s crust can be anywhere between __________________ and ____________________. The
thickest crust is usually ___________________________________________ crust, and the thinnest is usually
______________________________________________.
21. If an earthquake occurs less than 100km (65 miles) from the earthquake recording station, it is
said to be a _________________________________________ event. If it occurs between
___________________________ and _________________________ miles from the station, it is considered a
regional event. And if the earthquake happens farther than _____________________________ miles from the station, it
is called a teleseismic event.
22. At least _____________________ stations are needed to locate an earthquake’s epicenter.
23. ________________________________________________ waves cannot travel through Earth’s liquid outer core,
and _______________________________________________ waves get slowed down and bent. Between these two
situations, a __________________________________________________ zone, as shown in the diagram below is
created where no seismic vibrations make it through the Earth.
24. This zone is located from between
__________________________ and
_______________________ degrees in
either direction from the earthquake’s epicenter.
