Name that event
A sudden and rapid shaking of the ground
earthquake
Where is the focus of an earthquake?
Beneath the earth's surface
In the air high above the earth's surface
Wherever you feel the earthquake
beneath the earth's surface
Many volcanoes are located around this place in the Pacific ocean:
the Pacific plate (the ring of fire)
True or False?
Landslides can involve the entire side of a mountain -
TRUE
Can earthquakes be predicted?
YES
NO
NO
An opening in the Earth's crust that allows molten rock, gases, and debris to escape
volcano
Where is the epicenter of an earthquake?
Directly above focus
100 km away from the earthquake
Wherever the sensors are located around the globe
Directly above focus
Volcanoes are formed when this builds up inside the Earth and pushes upward (but never reaches the open air)
MAGMA
Can landslides occur underwater?
YES
NO
yes, landslides can occur underwater.
What is the fast speed of tsunamis?
600 km per hour
600 miles per hour = 965 km/hr
60 miles per hour
60 km per hour
600 miles per hour = 965 km/hr
dirt, pebbles, rocks and boulders suddenly slide down a mountain
landslide
What are vibrations from an earthquake called?
Seismic waves
3 places where volcanoes form:
1. divergent
2. convergent
3. hot spots
4. Transform
5. cold spots
6. earthquake faults
1. divergent
2. convergent
3. hot spots
True or False: Landslides are never small
False; sometimes landslides are small
Can animals sense tsunamis?
Yes, they move to higher ground before a tsunami strikes
A series of enormous ocean waves
tsunami
What is the science in which earthquakes are studied?
Seismology
Seismomography
Sizemolotry
Seismographs
Seismology (-ology is the study of anything)
Lava
How does gravity affect land to cause a landslide?
When gravity is stronger than the strength of the land
When gravity is weak and the land is strong
When strength of the land is stronger than wind and vibrations.
Landslides happen when gravity is bigger than the strength of the land
What does tsunami mean in Japanese?
harbor wave
big wave
baby wave
harbour vibrations
harbor wave

magnitude
Name the 3 life stages of a volcano
The 3 life stages of volcanoes are
1. active
2. dormant
3. extinct
Name 3 causes of a landslide
Heavy rainfall, volcanic activity, earthquakes, snowmelt, human activity (like construction)
Name 2 ways we monitor tsunamis
1. A recorder on the seafloor
2. data is transmitted to a surface buoy
3. data is relayed to a satellite
4. satellite transmits data to ground stations
All are correct:
1. A recorder on the seafloor
2. data is transmitted to a surface buoy
3. data is relayed to a satellite
4. satellite transmits data to ground stations
