Final Jeopardy


Earthquake activity l.jpg
Earthquake Activity

An American developed this scale to measure the magnitude of an earthquake.

Answer

Richter Scale


Earthquake activity3 l.jpg
Earthquake Activity

This is the action of wet soil acting like a liquid.

Answer

Liquefaction


Earthquake activity4 l.jpg
Earthquake Activity

These are ocean waves caused by an earthquake.

Answer

Tsunami or Seismic Sea Wave


Earthquake activity5 l.jpg
Earthquake Activity

Seismologists use this scale to measure the intensity of an earthquake. Based on the destruction caused.

Answer

Mercalli Scale


Earthquake activity6 l.jpg
Earthquake Activity

Name one warning sign of an impending tsunami.

Answer

Shoreline moves rapidly out to sea, exposing land that is usually underwater


Faults l.jpg
Faults

This type of fault is caused by tensional forces.

Answer

Normal Faults


Faults8 l.jpg
Faults

A reverse fault results from this type of force.

Answer

Compression


Faults9 l.jpg
Faults

Name the three types of forces that create faults.

Answer

Shear, Compression, Tension


Faults10 l.jpg
Faults

In this type of fault the rocks on either side move past one another with out much up or down movement.

Answer

Strike-Slip Fault


Faults11 l.jpg
Faults

Name an example of a strike-slip fault.

Answer

San Andreas Fault


Features of earthquakes l.jpg
Features of Earthquakes

These are the fastest seismic waves.

Answer

Primary Waves


Features of earthquakes13 l.jpg
Features of Earthquakes

These are generated by an earthquake and travel through the earth.

Answer

Seismic Waves


Features of earthquakes14 l.jpg
Features of Earthquakes

These types of waves are the slowest and cause the most destruction.

Answer

Surface Waves


Features of earthquakes15 l.jpg
Features of Earthquakes

This type of wave causes rocks particles to move at right angles to the direction of travel.

Answer

Secondary Waves


Features of earthquakes16 l.jpg
Features of Earthquakes

These waves move rock particles in a backward, rolling motion and a side to side, swaying motion.

Answer

Surface Waves


Earthquake terms l.jpg
Earthquake Terms

This is the point where the energy is just released.

Answer

Focus


Earthquake terms18 l.jpg
Earthquake Terms

This is the point on the earth’s surface directly above the focus where surface waves radiate outward.

Answer

Epicenter


Earthquake terms19 l.jpg
Earthquake Terms

To pin point the epicenter of an earthquake seismologists need to know the difference in arrival times of P and S waves and the location three of these.

Answer

Seismograph Stations


Earthquake terms20 l.jpg
Earthquake Terms

Rocks will break when pressure builds up and exceeds this term.

Answer

Elastic Limit


Earthquake terms21 l.jpg
Earthquake Terms

This is the boundary between the crust and the upper mantle.

Answer

Mohorivic Discontinuity or Moho


Slide22 l.jpg
MISC

Vibrations produced by breaking rock

Answer

Earthquake


Slide23 l.jpg
MISC

This is the paper record of an earthquake.

Answer

Seismogram


Slide24 l.jpg
MISC

Seismic waves bend or stop because of changes of this

Answer

Density or Materials


Slide25 l.jpg
MISC

The material that secondary wave cannot travel through

Answer

Liquid


Slide26 l.jpg
MISC

Because of bending and stopping of seismic waves this area is created.

AnswerShadow zones


Earthquake safety l.jpg
Earthquake Safety

Why would securing gas appliances help make your home earthquake safe?

Answer

To keep them from moving a great deal during an earthquake, which would cause a less of a chance for a gas line to break and leak gas
