Multiple choices
Vibrations in the earth caused by the sudden movement of rock are called:
Epicenters
Earthquakes
Faults
Tsunamis
The elastic rebound theory states that as a rock becomes stressed, it first:
Deforms
Melts
Breaks
Shifts positions
The point along a fault where an earthquake begins is called the:
Fracture
Epicenter
Gap
Focus
The point of the earths surface directly above the point where an earthquake occurs is called the:
Focus
Epicenter
Fracture
Fault
A characteristic of earthquakes that cause the most severe damage is:
a deep focus
An intermediate focus
A shallow focus
A deep epicenter
Most severe earthquakes occur
In mountains
Along major rivers
At plate boundaries
In the middle of plates
The boundary of the Pacific plate scrapes against that of the North American plate and forms
A single fault
A subduction zone
A volcano
A fault zone
P waves travel through
Solids only
Liquids and gases only
Both solids and liquids.
Liquids only
S waves cannot pass through
Solids
The mantle
The earth’s outer core
The asthenoshpere
By analyzing the difference in the time it takes for P waves and S waves to arrive at a seismograph station, scientists can determine an earthquake’s
Epicenter
L waves
Fault zone
Intensity
The Richter scale expresses an earthquakes
Magnitude
Location
Duration
Depth
Most injuries during earthquakes are caused by
The collapse of buildings
Cracks in the earth’s surface
The vibration of S waves.
The vibrations of P waves
If an earthquake strikes while you are in a car, you should
Continue driving
Get out of the car
Park the car under a bridge
Stop the car in a clear space and remain in the car
An earthquake is frequently preceded by
A temporary change in the speed of local P waves
A temporary change in the speed of the surface waves
Landslides
Tsunamis
Earthquakes with a very deep focus cannot be explained by the elastic rebound theory. Why?
If a seismograph station measures P waves but no S waves from an earthquake what can you conclude about the earthquakes location?
Two cities are struck by earthquakes. The cities are the same size, are built on the same type of ground, and have the same types of buildings. The city in which the quake measured 4 on the Richter scale suffered $1 million in damage. The city in which the quake measured 6 on the Richter scale suffered $50 million in damage. What might account for the difference in damage costs?
Would an earthquake in the Colorado Rockies be likely to form a tsunami? Explain.
5. Compare earthquake safety and tornado safety.
