What is a reverse fault?
One block of land stays in place, one block is pushed up
100
The scientists who study volcanoes are called...
Vulcanologists
100
What happens at a normal fault?
One block of land stays in place, one slides down
100
What is a tsunami?
A large ocean wave produced by an underwater earthquake
100
The two types of waves in an earthquake are...
S and P waves
200
What is a magma chamber?
Chambers/holes inside a volcano that can store magma
200
What are the three types of volcanoes?
Cinder cone volcano, shield volcano, composite/stratovolcano 
200
The scientists who study earthquakes are called...
Seismologists
200
The worst tsunami in recent history happened in...
Indonesia
200
What is a fault?
A crack in Earth's crust THAT IS NOT AT A PLATE BOUNDARY
300
Explain the theory of plate tectonics
Earth's plates are constantly shifting due to changes in pressure underneath Earth's surface
300
Tell me a real-life example of each type of volcano. 
Shield: Mauna Loa in Hawaii


Cinder Cone: Paracutin in Mexico


Stratovolcano: Mt. St. Helens in Washington 

300
What is the epicenter of an earthquake?
The place where the earthquake began
300
Does every earthquake cause a tsunami to happen? Explain. 
Earthquakes can only cause tsunamis if they happen UNDER WATER. 
300
What would happen if the supervolcano underneath Yellowstone erupted?
The entire United States would be covered in ash, it would get very cold, and a lot of living things could die
400
Explain the process of subduction
One plate goes underneath another plate, causing a hole to form
400
What types of volcanoes produce the deadliest eruptions?
Stratovolcanoes (composite volcanoes)
400
What is the name of the scale scientists use to measure earthquakes?
The Richter Scale
400
What are the four different causes of tsunamis?
Volcanoes, Earthquakes, Landslides, Meteor strikes
400
What kills the most amount of people during a volcanic eruption?
The smoke and ash
500
Explain the process of convection
Hot magma rises from underneath Earth's surface. When it hits the ocean floor it cools down and sinks, forming new seafloor. 
500
How can scientists predict when a volcano is going to erupt?
Earthquakes happen near the volcano and the volcano starts smoking
500
How can a 7.2 earthquake cause more people to die than a 9.0 earthquake? (HINT: Think of Haiti)
The more people there are in an area during an earthquake, the more people that will die
500
How can we make sure less people die during the next tsunami?
Better warning systems in place
500
Why do scientists need 3 stations to show where an earthquake happened?
3 stations help scientists to be more exact
