This is the device that records seismic waves.
What is a seismograph?
100
This volcanic landform is a hot spring in which water intermittently boils, sending a tall column of water and steam into the air.
What is a geyser?
100
This man created the theory of plate tectonics after seeing that Africa and South America not only fit together like puzzle pieces, but that they also had similar fossils on their shores.
Who was Alfred Wegener?
100
This is the region of the Earth that the plate tectonics float on.
What is the lithosphere?
100
What is the Ring of Fire?
200
This scale measures the magnitude of an earthquake.
What is the Richter Scale?
200
This type of volcano has not erupted for thousands of years and probably will not erupt again.
What is an extinct volcano?
200
At this type of boundary, plates move away from one another.
What is a divergent boundary?
200
The Hawaiian Islands are an example of these areas of volcanic activity that results from plumes of hot solid material that have risen from deep inside earths mantle.
What are hot spots?
200
The red line is this earthquake-prone region.
What is the San Andreas Fault?
300
This is where earthquakes occur.
What are transform boundaries?
OR
What are fault lines?
300
This type of volcano is a steep, cone-shaped hill or small mountain made of volcanic ash, cinders, and bombs piled up around a volcano's opening.
What is a cinder cone?
300
This is the name of the theoretical supercontinent that was all of the earth's land put together (Hint: It's name translates to "all earth" in greek).
What is Pangaea?
300
When one denser tectonic plate sinks beneath one less dense tectonic plate at a convergent plate boundary, this region is formed.
What is a subduction zone?
300
This is an example of an ______ _______ rock. (Bonus points for if you mention the name of the rock)
What is an extrusive igneous rock (and What is pumice?)
400
This is where, on the earth's surface occurs (Double points for if you name where in the earth, not on the surface where it occurs).
What is the epicenter? (and What is the hypocenter?)
400
This other natural disaster is often accompanied by volcanoes. They will occur before the eruption due to the tremors in the ground.
What are mudslides?
400
A continental plate and an oceanic plate are coming towards one another at a plate boundary. This is a ______-_________ ____________ boundary. (Triple points if you go into detail about what is occurring at the place the two plates meet and why).
What is a oceanic-continental convergent plate boundary? (and What is the oceanic plate, being denser than the continental plate, is pushed under in the subduction zone and is "recycled"?)
400
This is the type of fault where rocks on either side of the fault line move past each other sideways with little up or down motion.
What is a strike-slip fault?
400
Explain what is going on here and the name of the location (Hint: Remember the words of Bill Nye).
What is the Hawaiian hotspot? What is the hot magma builds up pressure beneath the plate and punches upwards as the plate slowly moves creating islands?
500
Name the three types seismic waves produced by an earthquake in the order they occur.
What are primary waves (P-waves), secondary waves (S-waves), and surface waves (Love waves and Rayleigh waves?
500
Mauna Kea is an example of a _______ volcano while Mt. Vesuvius is an example of a _________ volcano.
What is a shield and a composite (stratovolcano)?
500
Explain the Theory of Plate Tectonics.
(Something along the lines of) The Earth's lithosphere is made up of plates and these plates rest on the asthenosphere. The asthenosphere causes the plates to move. The movement of these plates leads to mountains, earthquakes, volcanoes, and much more!
500
This type of landmass occurs when the ocean floor is uplifted by magma at a divergent plate boundary.
What is a mid-ocean ridge?
500
What is this and explain how it works?
What is the Yellowstone Caldera? What is a massive explosion caused the volcano to blow a big hole in itself and the lava flows filling in most of the caldera?
