How many volcanoes does Illinois have?
1 (it is dormant)
100
Where is the largest volcano in the solar system?
Mars
100
Wave type that is longitudical
P wave
100
Highest point of a wave is called the
crest
100
In what city is the epicenter of this earthquake?
San Francisco
200
Where are most volcanoes in the U.S. located?
Alaska
200
What are the 3 types of lava flows?
AA
Pahoehoe
Pillow lava
200
Wave type that is transverse
S wave
200
Lowest point of a wave is called the
trough
200
Which city was most devastated by the earthquake?
Houston
300
What role does water play in volcano formations with oceanic plates?
It lowers the melting temperature, allowing the plate to melt and magma rise
300
Match the magma type to the characteristics:
Andesitic Basaltic Rhyolitic
1. Low viscosity/50% silica
2. Average viscosity/60% silica
3. High viscosity/70% silica
Andesitic: 2
Basaltic: 1
Rhyolitic: 3
300
Which color is the epicenter?
Blue
300
The distance between waves is the
wavelength
300
What damage do you think this earthquake caused?
Little-to-none
400
How is a hotspot different from volcanoes along plate boundaries?
Plate boundaries are where two plates meet. A plate subducts and melts causing magma to rise. A hotspot is an area of hotter magma that doesn't move.
400
What are the 3 different volcanoes and their characteristics?
Shield - broad base with gentle slope
Cinder cone - lava hardens around the vent, usually on side of larger volcanoes
Composite - tall and steep with explosive eruptions
400
What makes surface waves unique?
They are both longitudinal and transverse
400
The height or compression of the wave is the
amplitude
400
What's the S-P interval?
36 seconds
500
What are 3 conditions that allow magma to form?
1. Decrease in pressure
2. Increase in temperature
3. Increase in amount of water in asthenosphere
500
What are the 5 main types of debris/activity due to a volcanic eruption?
Ash
Lapilli
Block/bomb
Lahar
Pyroclastic flow
500
Label the 3 faults.
1: normal fault
2: reverse fault
3: strike-slip fault
500
Draw and label a transverse wave.
500
What's the amplitude of the S wave?
180mm
