What is the metric system?
This volcano is known for its broad dome shape
What is a shield volcano?
This scale is used to discuss the kind of damage an earthquake causes
What is the Mercalli scale?
He had the idea for how Pangaea broke apart and said the continents were being dragged along the seafloor by earth's gravitational pull
Who was Alfred Wagner?
What instrument do you use to measure the intensity of P waves and S waves of an earthquake
What is a seismometer?
Unit in the metric system used to measure mass
What is gram?

What is a composite cone?
These waves are the first to be released by an earthquake and the ground shakes back and forth
What are P waves?
Wagner's theory that was considered invalid because he could not prove what force was used to allow the continents to move
What is the Continental Drift Theory?
This volcano erupts while it is over a magma chamber and stops when tectonic plates move

What is the atmosphere, cryosphere, and hydrosphere?
Unit in the metric system to measure length
What is meter?
This volcano erupted long ago, killing thousands in the city of Pompeii

The actual location of an earthquake, located inside the earth's crust
What is the focus?
Who was John Tuzo-Wilson?
Scientists study this to better understand how the earth works and why things happen on Earth
What is the movement of plate tectonics?
When using the metric system, when you move to the right, this happens to the units
