Name:
Q1: A earthquake focus that is 50 km deep is considered to be a "deep" earthquake.
True
False
Q2: How do "seismic waves" occur?
Caused by the explosion of a powerful bomb
Caused by the vibrations of rock and earth movements at plate boundaries
Caused by Tsunami waves
Q3: When referring to earthquakes, what is a “fault?”
It is caused by two parts of the earth’s crust moving against each other over
a long period of time
A crater in the earth’s crust caused by a previous earthquake
A huge meteorite that crashed into the ground
Q4: What’s the “Richter Magnitude Scale”?
A calculation of the amplitude of the largest seismic wave released by an earthquake
A calculation of the strongest type of seismic wave
A calculation of the destruction caused by an earthquake
Q5: What scale is used to measure earthquakes?
Epicenter
Richter Scale
Fault Scale
Q6: What is the center of an earthquake as measured from the ground surface called?
Focus
Shake Center
Q7: What do scientists believe causes the most earthquakes?
Plates rubbing together
Meteorites hitting Earth
Built-up lava

Q8: Going up one whole unit on the Richter scale represents
a 10-fold increase in energy release
a 30-fold increase in energy release
