Ride the Wave 100
Which wave(s) travel through the
body of the earth?
P and S Waves
Ride the Wave 200
The first wave to arrive.
Primary waves
Ride the Wave 300
Which wave is most damaging?
Surface waves
Ride the Wave 400
Explain how scientists know the
outer core is liquid.
S-waves can’t travel through liquid.
The S-waves didn’t travel through
the outer core. Therefore, the outer
core is liquid.
Ride the Wave 500
Explain how you would find the time a
p-wave arrives on a seismogram.
Find the time the seismogram starts recording. Then count to
the p-wave. Each mark to the right represents 1 minute. Each
time you drop down a line it represents 30 minutes.
Plate Theory 100
Which part of the Earth has a taffylike texture and is ductile?
Asthenosphere
Plate Theory 200
At what plate boundary is land being
destroyed?
Convergent
Plate Theory 300
What is the name of the super-continent
that was thought to exist 200 million
years ago?
Pangea
Plate Theory 400
Why is the Atlantic Ocean getting
larger?
Sea-floor spreading at the midAtlantic ridge
(divergent boundary)
Plate Theory 500
Name 3 pieces of evidence for
continental drift theory.
1. Fit of Continents
2. Rock Evidence
3. Fossil Evidence
4. Climate Evidence
Sliding and Colliding 100
The San Andreas fault is this type of
plate boundary.
Transform
Sliding and Colliding 200
What is the name of the zone where one
plate slips under another?
Subduction Zone
Sliding and Colliding 300
When oceanic plate collides with
continental plate, what land forms
result?
Volcanoes and trenches
Sliding and Colliding 400
Which type of earthquake can
trigger Tsunamis?
Subduction Quake
Sliding and Colliding 500
Explain the difference between the
focus and epicenter of an
earthquake.
The focus is the exact point of the earthquake
(underground) and the epicenter is the point on
the earth’s surface directly above the focus.
Volcano Facts 100
Name the 3 main types of
volcanoes.
What is shield, composite, and
cinder cone.
Volcano Facts 200
Describe 3 features of a cinder
cone volcano.
What is smaller than the other
volcanoes, created from cinders
piling up, often has a crater.
Volcano Facts 300
Explain how volcanic eruptions can
affect global weather.
What is large quantities of ash are released
into the earth’s atmosphere. The ash stays in
the earth’s atmosphere, blocks out the
sunlight, and lowers the average temperature.
Volcano Facts 400
Name three negative effects of
volcanic eruptions.
What is ash decreases global temperature,
harms planes, bad for respiratory system,
causes collapse of buildings, lahars destroy
what is in the way.
Volcano Facts 500
Which volcano type is the most
explosive? Explain why it is.
What is a composite volcano. Composite volcanoes
have the most viscous lava (dissolved gases, rock
fragments). Since it doesn’t flow, the pressure builds
up and is released in an explosive eruption.
Monitoring & Effects 100
A machine used to measure
earthquake waves.
Seismograph
Monitoring & Effects 200
Name the paper that the waves are
recorded on.
Seismogram
Monitoring & Effects 300
The amount of energy released during
an earthquake is called the _______.
Magnitude
Monitoring & Effects 400
Name two ways scientists can tell a
volcanic eruption is nearing.
What is by monitoring earthquakes,
gas emissions, steam, volcano dome
growth.
Monitoring & Effects 500
What is a pyroclastic flow?
What is a flow of hot ash and gas
that rushes down a volcano after
an eruption.
FINAL JEOPARDY!
Where are the most explosive
eruptions located? What causes
them to be so explosive?
What is around the ring of fire? From
subduction. Crust is melted which is high in
silica so thick, sticky lava forms leading to
more explosive eruptions.
