Question | Answer |
---|---|
What does shearing in earths crust do? | Pushes the crust in opposite directions. |
when the hanging wall of a fault slips downward with respect to the footwall, the result is a | Normal fault |
What does a seismograph measure? | Ground motion during an earthquake. |
Geologists use the difference in the arrival times of P waves and S waves at a seismograph to determine | The distance to the epicenter. |
To monitor the upward movement along a fault, geologists would probably use a | Tiltmeter |
Deformation is the breaking,tilting, and folding of rocks caused by liquefaction. | F Stress |
Rock uplifted by strike slip faults creates fault block mountains. | F normal faults |
An earthquake's epicenter is located deep underground. | F Focus |
As S waves move through the ground, they cause it to compress and then expand. | F P waves |
Tsunamis are triggered by earthquakes originating beneath the ocean floor. | T |
How does stress affect earth's crust? | Compression,Tension, And shearing |
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 formation of folded mountains. | Compression |
Explain how the moment magnitude and richter scales of earthquake measurement are similar and how they are different. | They are both scales. The richter scale measures seismic waves. the moment magnitude measures earthquakes. |
What data do geologists collect when monitoring faults? | what kinds of seismic waves the earthquakes produce and how strong they are. |
How would you classify a fault in which the hanging wall has slid up and over the footwall. | A reverse fault. |
Compare and contrast S waves and P waves. | P waves come first S waves come second |
A community built a street across a strike slip fault. How would it damage the street? | It would damage it by big opening holes. |
If you were building a house on an earthquake prone area what would you do to limit potential damage in an earthquake? | Move from the fault line. |
