| Question | Answer |
|---|---|
| shearing is the force in earth's crust that is | pushes mass of rocks in two opposite |
| when the hanging wall of a fault slips downward with respect to the footwall the result is a | normal fault |
| a seismograph measures | records floor movement |
| geologists use the difference in the arrival times of p waves and s waves seismograph to determine | the distance of the epicenter |
| to monitor the upward movement along a fault geologist would probably use a | tiltmeter |
| true or false deformation is the breaking tilting and folding of rocks caused by liquefaction | stress |
| true or false Rock uplifting by strike-slip fault creates fault-block mountains | normal faults |
| true or false an earthquake's epicenter is located deep underground | focus |
| true or false as s waves more through the ground , they cause it to compressed and then expand | p waves |
| true or false tsunami are triggered by earthquakes originating beneath the ocean floor | true |
| how does stress affect earth's crust | it can create mountains hills and massive gaps |
| Explain the process that forms a fault-block mountain | when normal faults uplift a block of rock |
| What type of stress in the crust results in the information of folded mountains? Explain your answer. | Compression because, it pushes the ground together. |
| What are plateaus and how do they form. | Plateaus are large area of flat land elevated high above sea level. Plateaus form when vertical faults push up large,flat block of rock. |
| Explain how the moment magnitude and Richter scales of earthquake measurement are similar and how they are different. | Both scales can detected earthquakes but magnitude scale can detected any size earthquakes and Richter scale can detected small earthquakes. |
| when geologists monitor a fault what kinds of data do they collect, explain | waves |
