This is the study of earthquakes.
What is seismology?
At a convergent boundary between ocean crust and continental crust, this is the crust that is pushed under.
What is ocean crust?
These are waves of energy that go though the Earth; cause by earthquakes.
What are seismic waves?
This magnitude earthquake causes near total destruction and seismic waves can be seen to the naked eye.
What is magnitude 9 or higher?
If outside during an earthquake, stay away from....
What are buildings?
or What are power lines?
or What are trees?
etc
These are large pieces of Earth's crust.
What are tectonic plates?
This is where most earthquakes occur.
What is near tectonic boundaries?
or What is the Ring of Fire?
Daily Double
Instrument on Earth's surface that records seismic waves.
What is seismograph?
This magnitude earthquake can only be felt by seismographs.
What is magnitude 1?
After an earthquake there can be smaller earthquakes. These are called...
What are aftershocks?
Large waves caused by earthquakes or landslides that occur in the ocean.
What is tsunami?
This tectonic boundary causes medium earthquakes.
What is a transform boundary?
This seismic wave is slower, only goes through solids, and moves side to side.
What is S- Wave?
or What is Secondary waves?
This magnitude earthquake destroyed bridges and few structures are left standing.
What is magnitude 8?
Daily Double
This is the safest place to go if you are indoors and there is an earthquake.
What is under a table?
Daily Double
This is a crack in Earth's surface.
What is a fault?
This tectonic boundary causes weak earthquakes.
What is divergent boundary?
This is the fastest seismic wave.
What is P-wave?
or What is Primary Wave?
Daily Double
This magnitude earthquake causes damage to well-built buildings.
What is magnitude 6?
Before an earthquake TVs and cabinets should be...
What is secured to the wall?
The point on Earth's surface directly above where the earthquake began.
What is epicenter?
Daily Double
This tectonic boundary causes strong earthquakes.
What is a convergent boundary?
This type of seismic wave causes the most damage.
What is surface wave?
This magnitude earthquake may cause windows to break.
What is 4?
If you are in your car and there is an earthquake, this is the safest thing to do.
What is stop and stay in the car?
