Basalt and Obsidian are examples of this rock, which is formed from "fire"
What is igneous rock?
100
A stratovolcano in Washington State that erupted in 1980 (very famous).
Mt. St. Helens
100
A device used to measure the magnitude of an earthquake.
What is a seismograph?
100
This is the engine that drives plate motions.
What is mantle convection or heat rising?
100
This is the most powerful "agent" of erosion (with gravity's help)
What is water?
200
This process occurs deep within the earth and is associated with the formation of metamorphic rocks.
What is heat and pressure?
200
Yellowstone is this type of volcano
What is a supervolcano OR caldera?
200
Waves that can be measured from seismograph data to determine lag time and ultimately distance to the epicenter.
What are P and S Waves?
200
This is evidence that supports that plates have moved and used to be all together as one continent.
What is similar fossils found on both South America and Africa?
200
Glaciers once covered this amount of Vermont.
What is the entire state?
300
Process that creates sedimentary rocks from sediment.
What is compacting and cementing?
300
Geologic hazard that is closely associated with the possible eruption of Mt. Rainier (and has happened in the past 500 hundred years).
What are lahars?
300
A plate boundary type associated with high earthquake activity.
What is a transform plate boundary OR fault?
300
This is when an oceanic plate goes under a continental plate.
What is subduction zone?
300
This is an example of weathering/erosion occuring within seconds, as opposed to millions of years.
What is a flood/landslide/avalanche?
400
A specific example of this rock type is sandstone.
What is sedimentary rock?
400
Eruptions of these volcanoes usually include fire fountains and rivers of very runny lava.
What are shield volcanoes?
400
Second largest earthquake in recorded world history.
What is the 2010 Chile earthquake?
400
When any two plates are moving away from each other.
What is a divergent plate boundary?
400
These are the gigantic boulders that glaciers often times leave behind; they pick them up as they advance and then drop them far from their origin as the glacier retreats. They are out of place.
What are glacial erratics?
500
Vermont is one of the leading producers of marble, which is this type of rock.
What is metamorphic?
500
This is geologic feature that creates volcanoes on the islands of Iceland and Hawaii, in addition to the Yellowstone Volcano.
What is a hot spot?
500
Earthquakes can cause this hazard to occur, which threatens areas like Japan and Hawaii.
What is a tsunami?
500
This is the layer of earth that contains plates; these plates then "float" on another layer.
What is the lithosphere?
500
This is when water gets into small cracks of rocks, which subsequently freezes, breaking apart the rock (because water expands when it freezes).
