Terms
100
Where do volcanoes usually form?
What is at plate boundaries (continent edges and in the ocean at boundaries)
100
Where do most earthquakes occur?
What mostly at the edges of continents/plate boundaries.
100
A break in Earth's lithosphere where plates move is called what?
What is a fault.
100
Which scale measure the magnitude of an earthquake?
What is the Richter scale.
100
How did scientists determine the outer core was liquid? (Yes, I know this is not a term- cut me some slack!)
What is the S waves (secondary waves) could not travel through it.
200
What is volcanic ash made of?
What is particles of pulverized rock ad glass.
200
Which earthquake waves travel deepest into the center of the Earth?
What is P waves (primary).
200
In what three ways can plates move to cause earthquakes?
What is horizontally, away, or toward each other.
200
If you say:" the chimney fell over and the driveway cracked", what earthquake measuring scales are you using?
What is the Modified Mercalli Scale
200
Instrument the records seismic activity?
What is a seismometer.
300
Why does magma move to the surface?
What is magma is less dense than the rock, so it is forced toward Earth's surface.
300
Which waves are first to reach a seismograph after an earthquake?
What are p waves (primary)
300
In what type of fault do rocks on either side of the fault surface move past each other?
What is strike-slip.
300
What do S waves (secondary) do when they hit the liquid outer core?
What is they stop.
300
What scale is used to describe the amount of energy and earthquake releases?
What is the moment magnitude scale.
400
Which type of volcanic lava flow is the hottest and fastest moving?
What is pyroclastic.
400
The point in Earth's interior where the energy release of an earthquake occurs?
What is the focus.
400
At what type of plate boundary does a normal fault occur?
What is divergent/ where the plates pull apart.
400
What are people that study earthquakes called?
What is seismologists.
400
What are waves called that travel outward from the epicenter?
What are S waves (surface).
500
In what way do volcanic eruptions affect the climate?
What is they cause a global temperature decrease.
500
Most of the destruction in an earthquake is caused by which of the three types of waves?
What is surface waves.
500
In what type of fault do two plates slide horizontally past each other?
What is a strike-slip fault.
500
How many seismograph are needed to accurately locate an earthquake epicenter?
What is three.
500
What term describes the graph illustration of an earthquake (I made this on the white piece of paper, and they are posted in the hallway)?
What is a seismogram.
