Earthquakes
These are breaks in the earth's surface along which rock can move.
What are faults?
Most of earth's volcanos are found here: (hint not looking for the ring of fire.)
what is underwater.
Some scientist believe that at one time the earth could have been a single large landmass known as:
What is Pangea?
These seismic waves occur beneath the surface of the earth.
What are body waves.
what is dormant composite cone volcano.
What is the beginning point of an earthquake called?
What is the focus.
This location of active volanoes around the edges of the Pacific Ocean is called...
What is:
The Ring of Fire.
Who first formulated the idea of Plate Tectonics?
Who is Alfred Wegener.
Which waves are the most destructive in relation to earthquakes?
What are surface waves.
This is a large gradual sloping volcano...
What is composite cone.
these are vibrations of energy that flow out from the beginning point of an earthquake.
What are seismic waves.
What is the difference between lava and magma?
What is:
Lava is magma that has reached the earth's surface.
Magma is below the surface.
The theory that the earth's crust is made of moving plates
What is The Theory of Plate Tectonics.
These are the most violent volcanic eruptions.
What are Plinian eruptions.
Define: Active, Dormant, Extinct in relation to volcanos?
What are:
Active:erupted at some point during the recorded time period and expected to erupt again.
DORMANT: HAVE erupted in the distant past, but are currently inactive and not expected to erupt again.
EXTINCT: does not have a recorded eruption and is not expected to erupt in the future.
These are a series of giant wave caused by a earthquake, volcano, or landslide occurring under or near the ocean.
What are tsunamis.
These are underwater volcanic eruptions.
What are submarine eruptions.
the lithosphere contains:
pockets of magma chambers.
Mix of volcanic ash and fog.

Name the three types of Volcano by Shape: p. 16
What are:
Shield - gentle slope, some of largest in world.
Composite Cone - Symmetrical cone shaped, resembles a hill more than a volcano. explosive eruptions
Cinder Cone - hill shaped with bowel like crater. steep sides. explosive eruptions.
What is the difference between the Mercalli Scale and the Richter Scale.
What is:
Mercalli - Measures damage done to surrounding buildings and manmade structures.
Richter Scale - Measures the magnitude of the waves produced by the earthquake.
What is the difference between Hawaiin, Plenean, and Plinian Eruptions?
Which is the most Violent?
Most Passive?
What is:
Hawaiin - quite, runny lava; little or no cinder, ask or steam.
Pelean - avalance of red-hot dust and gases; pyroclastic flow.
Plinian - most powerful/violent eruption, spewing lava, gas, and dust into the atmostphere.
Plinian is most violent; Hawaiin is quite...
What are the three types of rock and what are the "keywords" associated with each?
What are
Metamorphic - Heat and Pressure
Igneous - hardened/cooled lava/magma.
Sedimentary - "layers"
What are the three types of faults AND how do they move?
What are:
Convergent - move towards each other.
Divergent - move away from each other
Transform - slide horizontally past each other.
Three ways an earthquake may form:
Pg. 7 in Textbook.
What are:
1. Adding or removing large amounts of earth.
2. movement of plates.
3. movement of molten rock under a volcano can also be a cause.
