Volcanoes
Miscellaneous
Earthquakes
Plates (not the kitchen kind)
100
This type of volcano is made from low viscosity magma and are among the biggest on Earth.
What are shield volcanoes
100
Wegener hypothesized that the Earth's continents used to be connected in one supercontinent called this.
What is Pangaea.
100
Earthquakes most often occur along this type of plate boundary.
What is transform boundary.
100
Wegener created this theory of how plates move.
What is plate tectonics.
200
This type of volcano has violent eruptions.
What is a composite volcano.
200
Mount St. Helens is this type of volcano.
What is composite volcano.
200
The spot deep in the Earth's crust where an earthquake begins.
What is the focus
200
Mountains form at this type of plate boundary.
What is convergent continental/continental.
300
A primary cause of volcanic eruptions is that this decreases as magma moves from deep in the Earth to the surface.
What is pressure.
300
Hawaii is an example of this type of volcanic formation.
What are hot spot volcanoes (or intraplate).
300
The spot directly above the focus found on the surface of the Earth.
What is the epicenter.
300
These are formed along oceanic-continental convergent boundaries.
What are volcanoes.
400
Hot spot volcanoes are formed when the hot upwelling of magma stays in one place and this moves over the top.
What is a plate.
400
Hawaii's islands get smaller as they move away from the hot spot because of these processes.
What are weathering and erosion.
400
These carry the energy released by the earthquake.
What are seismic waves.
400
Mid-ocean ridges are an example of this type of plate boundary.
What is a divergent boundary.
500
The viscosity of magma depends on these 3 factors.
What are temperature, water content, and silica content.
500
The most well known measurement scale for measuring the strength of earthquakes.
What is the Richter scale.
500
A break in a mass of rock along which movement occurs. You can find a famous one of these in California.
What is a fault.
500
This process creates new oceanic crust at mid-ocean ridges.
What is seafloor spreading.
