Jaeden Science Chp.2

QuestionAnswer
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.
