True or False: Volcanoes form at underwater convergent plate boundaries.
True
100
What can form a tsunami?
Underwater earthquake, volcanic eruption, landslide, meteor impact
100
What are the three plate boundaries that earthquakes are formed?
Convergent, divergent, transform
100
What does Tsunami mean
harbor wave
100
Draw a shield volcano and label if it has high or low viscosity
low
200
Hawaii was formed by a ...
hot spot in the pacific ocean
200
What is the maximum velocity a tsunami can travel?
500-600 mph
200
What is an earthquake?
When the earth shakes due to a release of pressure along a fault
200
What does viscosity mean?
resistance to flow
200
draw a cinder cone volcano and say if it has high or low viscosity
high
300
What type of viscosity does a composite volcano have?
high viscosity
300
How can an earthquake cause a tsunami?
A plate snaps up at a subduction zone, causing a great displacement of water
300
What is the most famous fault in California? Name it and what type of plate boundary is it?
San Andreas Fault - Transform Boundary
300
What does velocity mean?
speed (how fast something moves)
300
draw a composite volcano and say if it has high or low viscosity
high
400
What is the difference between a cinder cone volcano and a shield volcano?
Cinder Cone: Large opening at the top and a high viscosity Shield : has a low slope and a low viscosity
400
As a tsunami travels through deep water is (gains / loses) speed.
Gains
400
What is it called when water is squeezed up from the earth during an earthquake?
Liquifaction
400
Where are most volcanoes, earthquakes, and tsunamis found?
Ring of Fire - Pacific Ocean
400
draw how a volcano is formed along a oceanic - continental convergent boundary (label the plates)
see the board
500
What three plate boundaries can form a volcano? Be specific: name the types of plates
Oceanic - continental convergent boundary Oceanic - oceanic convergent boundary oceanic - oceanic divergent boundary
500
What is the most common natural warning sign a tsunami is coming?
The tide rushes out
500
The break in the Earth where earthquakes happen are known as...
a fault
500
What are 3 difference between a tsunami and a surface wave?
tsunami: travels 500-600 mph, 500-100 feet tall, moves the whole water column of water, doesn't crash at the shore Surface Wave: travels 30-40 mph, about 6 feet tall, only moves the top surface of the water, crashes at shore
