Earthquake Test Study Guide
Test is the Friday. Make time to review your notes.
1) What is the cause of earthquakes?
2) What is a fault?
3) Where is the focus of an earthquake?
4) Where is the epicenter of the earthquake?
5) Name the three types of earthquake waves.
6) Which seismic wave has a push-pull movement?
7) Which seismic wave has a wriggling side to side motion?
8) Which seismic wave causes the most damage during an earthquake?
9) Which seismic wave does not travel through liquids?
10) Which seismic wave travels through the all layers of the Earth?
11) Know which waves move through the earth’s interior (body) and what happens to seismic waves as they
travel through materials of different densities. (See Seismic wave graph).
12) Which seismic wave travels only on the surface of Earth?
13) What is one way that scientists know the outer core is liquid?
14) What is the main source of energy that causes earthquakes?
If looking at three seismograms of the same earthquake from three different seismograph stations, be able to…
15) The earthquake was nearest to which city?
16) When did the first P-wave arrive in Los Angeles?
17) Why are the times the earthquake arrived at each city different?
18) What does the Richter scale measure?
19) What is the difference in wave amplitude of an earthquake that measures 4.0 on the Richter scale, to an
earthquake that measures 5.0?
20) What does the Mercalli scale measure? (Intensity)
21) How many seismograph readings (wave travel time data) are required for scientists to locate an earthquakes
epicenter?
22) Know which is denser, oceanic or continental crust.
23) Name the parts of the Earth’s interior. Know the terms lithosphere, crust, asthenosphere, mantle, outer core,
inner core.
24) What part or parts of the earth make up the lithosphere?
25) Name different ways that mountain ranges can form?
26) List evidence used by Alfred Wegner to support the idea that the continents were once one landmass?
27) Be able to identify where an earthquake is, if given its latitude and longitude.
28) Study your plate tectonics map. Know where plates are spreading at the mid- ocean ridge, where plates are
sub-ducting, and where plates are colliding. Know the type of boundary that seafloor spreading occurs at.
29) Know where the youngest rock can be found on earth.
30) Be able to identify the San Andreas fault in California is a transform fault involving the Pacific Plate and the
North American Plate. Know which way each plate is moving. Name the famous Creek that the San
Andreas Fault changes. Know how transform boundary movement effects fences, rivers, and other
structures on the land along the fault and they can change shape as a result of the forces created by the
moving plates.
31) Know how islands can form.
32) Know the name of the process that causes movement of tectonic plates.
