Volcanos and Earthquake Review

Any force that results from gravity or plate motion is called

• strain
• stress
• deformation
• fault

S waves can only travel through 

• solids
• liquids
• gases
• plasma

You would find the most destruction

• 10 miles from the epicenter 
• 30 miles from the epicenter
• 100 miles from the epicenter
• At the epicenter

A crack in a body of rock that the rock can move along is called a

• P waves
• Earthquake
• Fault
• Fault-Block Mountain

Which of the following DOES NOT describe an S waves?

• S waves can travel through solids
• S waves arrive second to the seismograph station
• S waves expand and contract
• S waves move side to side and up and down

Mountains that form when one block drops relative to another or one block is pushed up relative to another is called

• Folded Mountain
• Fault-Block Mountain
• Valley Mountain
• Tectonic Mountain

If large-scale folding occurs over a large geographical region, what will most likely form there?

• A reverse fault
• A fault black mountain
• A strike-slip fault
• A folded mountain

Which of the following is found below the surface when the rock breaks along the fault?

• Focus
• Epicenter
• Stress
• Deformation

What information from seismographs do scientists use to calculate the distance to an earthquakes epicenter?

• The frequency of P waves
• The direction of P waves
• Difference in the wavelengths of P waves and S waves
• Difference in arrival times of P waves and S waves

Which statement best describes the effect of P waves on rock?

• They carry rock away from the epicenter of an earthquake
• The carry rock away from the focus of an earthquake
• They move rock in a back and forth motion parallel to the force
• They move rock in a back and forth motion perpendicular to the force
