True or False: Volcanoes form at underwater convergent plate boundaries.
True
100
What can form a tsunami?
Underwater earthquake Volcanic Eruption, Meteor Land slide
100
What does "P" waves travel through?
Liquid and Solid
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
200
What is the maximum velocity a tsunami can travel?
500-600 mph
200
What do "S" waves travel through?
Solid
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?
Subduction, plate snaps up causing a great displacement of water
300
Which wave travels faster and always arrives first?
P waves
300
What does velocity mean?
speed ( how fast something is)
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 volcano has a large opening at the top and has a high viscosity Shield Volcano has a low slope and a low viscosity
400
As a tsunami travels through deep water it (gains / looses) speed.
gains
400
Draw the difference between the way p waves and s waves move
p waves : <---> , --><--, <--- ---> (forward and backward) S waves: ~~~~~~~~~~~~ (side to side)
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 drawing on the board
500
What three plate boundaries can form a volcano? Be specific: Name the types of plates
Continental - Oceanic Convergent Oceanic - Oceanic Convergent Oceanic - Oceanic Divergent
500
What is the most common natural warning sign a tsunami is coming?
The tide rushes out
500
How do scientists know the outer core is liquid?
S waves can't travel through the outer core
500
What are 3 differences between a Tsunami and a Surface wave?
Tsunami: travels 500-600 mph, 50-100 feet tall, moves the whole column of water, doesn't crash at shore Surface Wave: Travels 30-40 mph, about 6 feet tall, only moves the top surface of the water, crashes at shore
