Science test Flashcards
Do scientists have the technology to predict earthquakes and warn people days in advance
No
are most eartquakes too gentle for people to feel
yes
can slippin of a fualt plate tectonics and eruption of a volcano all caus an earthquake
yes
Does the force a rock exerts as it strikes a roadway after tumbling down a hill involve tension
no
Does the froce a rock climber exerts on the rope as he rappels down acleff involve tension
yes
does the sliding o two layers or rock across each other during a mudslide involve tension
no
does the rolling of arock along the bottom of a raging river involve tension
no
what type of stress is the most significant in causing earthquakes
shear
what is a series of low frequency shock waves traveling through the earth called
earthquake
do modern seismologists believe that fault and eathquakes are caused by tectonic faults
yes
Subduction or collision would most likely be occuring at what kind of boundary
convergent
At ______ boundaries, the plate are moving aart
divergent
at _______ boundaries plates are coming toward each other
convergent
________ boundaries have plates sliding past each otther in opposite directions
transform
Do all types of rock when under strain, respond in the same way
no
What is the major difference between a fualt and a joint
A fault is when an opposite sides of the crakc move relative to each other and a joint are the cracks in a rock
what is acrakc in arock where movement has occure
faults
where are most major faults in the United Sates found
mountian ranges q
what is a transform fault called
long strike slip
which of these is true a locked fault must e a dip slip fault. a reverse fault is a type of dep slip fault. a normal fualt is atype of strike slip fault. a transform fualt is atype of dip slip fault
a reverse fault is a type of dep slip fault
what is the name of the longest strike slip fault in southern california
san andreas
What are the smaller secondary eathquakes that result from a jamor eathquake called
aftershocks
do water and cetain types of minerals act as a natural lubricant to prevent a fulat from becoming locked
yes
does a seismograph include both a seismometera and a device that records or grpahs seismic movements
yes
a speial geologist who studies the earth’s movements and the structure of interior is called
seismologists
are the last waves to reach distant seismographs the s waves
no
what is the fastest body wave
P waves
what is a body wave that cannot ravel through earth’s core
S waves
do different types of seismic waves travel only on the earth’s surface
yes
do different types of seiemic eaves travel through the earth including the core
yes
Do differeent types of seismic waves travel through the eart but not to the core
yes
rayleigh waves and love waves are both examples of what type of waves
surface waves
what is the center of earthquake activity called
focus
what is the point of earth’s surface above the center of earthquake activity
epicenter
are only two seismic stations needed to pinpoint anearthquake’s epicenter
no
do some earthquakes occur along faults that are not tectonic boundaries
yes
what type of fault do most secular geologists believe could explain how older fossils were placed above younger fossils
overthrust
one quake measures 6.0 and another quake measures at 7.0 on the Richter scale. How does the second quake’s intensity compare with that of the first
31.6 times more energy released
what is the energy of an earthquake called
magnitude
what is used to express an earthquakes magnitude
Richter scale
Does the richter scale go from 1 to 8
no
which one of these terms does not belong with the rest modified mercalli intensity moment magnitude richter rayleigh
rayleigh
Theoretically, could a very intense earthquake be felt by every person on the eath
yes
what is an ocean wave caused by an earthquake
tsunamis
have architects desinged buildings that can withstand and earthquake with a magnitude of 8.0
yes
are tsumamis often called tidal wavs because they are caused by tides
no
