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.
