Allie's Ch. 8 Quiz
this quiz, test etc really helps you study for the ch 8 science test!
Terms
undefined, object
copy deck
- elastic deformation
- when the rock can only be stretched to a certain point before breaking(does lead to e quakes)
- transform
- 2 plates slide past each other
- underneath a desk or table
- Where should you go during an e quake while inside?
- tectonic plates
- peices of the lithosphere that move on top of the atenosphere
- subduction zone
- 1 plate sinks below the other
- surface wave
- Wave which causes rock particles to move in a backward rolling and side to side swaying motion, this is the most destructive earthquake wave
- convergent
- 2 plates collide
- fault
- a break in the earths crust
- solar flares
- what are the moon, mars, and sunquakes caused by?
- s waves
- waves of energy that travel through earth
- compression
- occurs whaen an object is squeezed
- California
- Where is the highest earthquake hazard area?
- divergent
- 2 plates move away from each other
- foot wall
- fw moves up compared to the hw
- tension
- occurs when an object is stretched
- seismogram
- tracing of earthquake motio0n created by a seismograph
- Moho
- a place in the earth where seismic waves speed up
- 9.1 on the richter scale
- How strong was the earthquake in north america?
- seismology
- the study of earth quakes
- folding
- occurs when rock layers bend due to stress
- epicenter
- the point on the earths surface right above an e quakes focus
- seismologist
- a person that studies e quakes
- e quake on mars
- Marsquake
- pacific ring of fire
- seiries of volcanic mtns. surrounding the pacific ocean
- they thought there was a huge marsquake because of the heavy wind
- what happened on mars when scientiststried to use a seismograph
- mantle and core
- what is moho a boundary for?
- along or near the edges of tectonic plates
- where do e quakes occur?
- hanging wall
- hw moves up compared to to the fw
- March 27,1964 in Alaska
- What was the highest recorded earthquake in North America?
- e quake on the moon
- Moonquakes
- seismograph
- an instrument located at or near the surface of the earth that records seismic waves
- plastic deformation
- like a peice of molded clay or in an elastic manner like a rubber band
- the colliding of tectonic plates
- what causes earth quakes
- 4 tsunamis
- how many tsunamis followed after the strongest recorded e quake in north america?
- 215,000 square kilameters
- how many square kilameters did Alaska raise or lower?
- focus
- the point inside the earth where an e quake begins
- measures magnitude
- what does the richter scale do?
- 10 meters
- how many meters was Montague island raised by?
- reverse fault
- hw moves up; fw moves up
- seismometer
- a device that measures the actual movements of the ground.
- e quake on sun
- Sunquake
- strike/slip fault
- one side of the fault moves from left to right
- fault blocks
- blocks of crust on either side of a fault
- p waves
- travel thru solids,liquids, and gases ,fastest seismic waves
- elastic rebound
- the sudden return of deformed rock to its original shape
- deformation
- when rocks change its shape due to stress
- 3 at the minimum
- how many machines does it take to get to the center of an earthquake?
