which seismic waves compress and expand rocks in the direction the waves travel?
P waves
what kind of plate boundary occurs where two plates grinds past each other without destroying or producing lithosphere.
transform fault boundary
why do earthquakes often cause damaging fires?
earth vibrations can break gas lines, water lines, and electrical lines.
tensional stresses commonly cause which of the following?
normal faults
what volcanic feature is illustrated at A in figure 10-2?
continental volcanic arc
what type of plate boundary resulted in the volcanic activity illustrated in figure 10-2?
oceanic-continental convergent plate boundary.
a fault in which the hanging wall moves down relative to the footwall is a
normal fault
what type of volcano is built almost entirely from ejected lava fragments?
cinder cone
the particles produced in volcanic eruptions are called?
Pyroclastic materials
what feature is labeled A in figure 10-1
pipe
what type of volcano is illustrated in figure 10-1?
composite cone
a tectonic plate consists of
the crust and uppermost mantle
which of the following can be produced at an ocean-continental convergent
continental volcanic arc
earthquakes are usually associated with?
faults
what is the most abundant gas associated with volcanic activity?
water vapor
an earthquake epicenter is
the place on the surface directly above the focus
the richest magnitude of an earthquake is determined from the
measurement of the amplitude of the largest seismic waves
which of the following factors helps determine whether a volcanic eruption will be violent or relatively quiet.
all of the above
a lava flow with a surface of rough, jagged blocks and sharp, angular projections is called an
aa flow
the board, slightly dome-shaped volcanoes of Hawaii are
shield volcanoes
faults in which movement is mainly horizontal and parallel to the trend of the fault surface are called
strike-slip faults
in figure 3-1, what process or processes would be occurring in the part of the rock cycle.
compaction and cementation
in figure 3-1, what type of rock should occur in the part of the rock cycle. labeled f
sedimentary
According to the theory of plate tectonics,
the lithosphere is divided into plates
the Hawaiian island were formed when the pacific plate moved over
a hot spot
a tsunami can occur when there is vertical movement at a fault under
the ocean floor
overall, which seismic waves are the most destructive?
surface waves
what forms when one oceanic plate is forced beneath another plate
a subduction zone
when an earthquake occurs, energy radiates in all directions from it’s source, which is called
focus
the super continental int he Continental drift hypothesis was called
Pangaea
through which earth layer are s waves NOT transmitted
outer core
one kind of evidence that supports Wegener’s hypothesis is that
fossils of the same organism have been found on different continents
the Himalaya in south Africa are an example of what of what type of plate boundary
convergent continental-continental boundary.
where is the energy source found that dives the process that forms igneous an metamorphic rocks
earth’s interior
which of the following is not a rock.
magma
most of the active volcanoes on earth are located in a belt known as the
ring of fire
what is the name of the major strike-slip fault in California
San Andreas fault
according to figure 8-1, when will the first p wave be received, if an earthquake epicenter is approximately 1800 kilometers from the seismic station.
3.5 minutes after the earthquake
according to figure 8-1, what is the distance between the seismic station and an earthquake epicenter, if the first s wave arrives 4.0 minutes after the p wave
2500 kilometer
