• None of the above.

This famous transform fault is located in the western United States creates significant earthquake activity for California

• Sierra Nevada Seismic Zone

• San Fransisco 
• San Andreas

The huge pieces of the earth's crust are called ____________________________. 

• crust
• plates
• directions
• seismos

The Modified Mercalli scale rates the amount of damage from an earthquake

• true
• false

The Richter scale measures:

• the amount of radon gas released
• the movement of plates
• the strength of an earthquake
• the weight of tectonic plates

The magnitude of an Earthquake is......

• a fault line
• The amount of energy released by the Earthquake
• The amount of damage done by the Earthquake

As the distance from the epicenter increases......

• intensity increases
• intensity decreases
• magnitude decreases
• all of these

______________ is the amount of damage done to structures by the Earthquake.

• Probability
• Amplitude
• Seismic Gap
• Intensity

The numerical scale used to measure an Earthquakes magnitude

• Moment-time
• Richter
• Mercalli

• 1 time bigger
• 10 times bigger
• 100 times bigger
• 1000 times bigger
