A)  convergence. 
B)  transform. 
C)  extension. 
D)  epicenter. 
E)  focus.

Question 2

What is a fault? What different types of faults are there?

Accepted Answer

A fault is a fracture or zone of fractur

Question 3

There are different scales for measuring earthquakes. Describe the (1) Richter Scale and the (2) Modified Mercalli Scale. Why do geologists need different scales for measuring earthquakes? How are they useful?

Accepted Answer

The Richter Scale is a logarithmic scale

Question 4

Surface waves travel slower than body waves and are a major cause of shaking and damage to structures.

Accepted Answer

A) True 
 B)False

Question 5

What is the theory for how earthquakes work in which rocks are strained and then suddenly break?

Accepted Answer

A)  elastic rebound 
B)  plate tectonics 
C)  creepy faults 
D)  seismology 
E)  epicenter 
A)  elastic rebound 
B)  plate tectonics 
C)  creepy faults 
D)  seismology 
E)  epicenter

Question 6

What is liquefaction?

Accepted Answer

A)  a process that occurs when rocks fall from a cliff 
B)  a process that occurs when rocks slide past each other along a transform plate boundary 
C)  a giant sea wave that can be triggered by an earthquake 
D)  a large change in elevation that occurs during an earthquake 
E)  the behavior of soils that, when shaken by an earthquake, suddenly cannot bear loads and act as a liquid

Question 7

Will an earthquake cause California to fall off into the ocean?

Accepted Answer

A)  No. The San Andreas Fault System in California is the boundary between the Pacific Plate and North American Plate. The plates are moving horizontally past one another, so California is not going to fall into the ocean 
B)  Yes. Eventually a large enough earthquake will occur along the San Andreas Fault in the Los Angeles area, causing the entire state of California to fall into the ocean. 
C)  Yes. People in California should move to Oklahoma, or another state where no earthquakes happen. 
D)  Yes. Crevasses can form during earthquake, and a magnitude 8 earthquake can trigger one as big as the State of California. 
E)  Yes. Earthquakes can trigger volcanoes, which can erupt and cause tsunamis, causing California to fall into the ocean.
