Mystery ?
100
The name of the "Super Continent".
What is Pangaea?
100
3 types of mountains
What is folded, fault-block, & dome?
100
Most volcanoes occur in a large belt that encircles this.
What is the Pacific Ocean?
100
The strength of an earthquake's seismic waves.
What is it's magnitude?
100
A smaller quake that follows a big earthquake.
What is an aftershock?
200
The idea that the earth's landmasses were once just one large land mass.
What is the theory of continental drift?
200
Made from the force of the plates pushing against each other causing the crust to bulge until "waves" of mountains are formed.
What is a folded mountain?
200
The belt where most volcanoes occur.
What is The Ring of Fire?
200
This measures the magnitude of an earthquake's seismic waves from 1 to 10.
What is the Richter scale?
200
A machine that measures the strength of the seismic waves in an earthquake.
What is a seismograph?
300
The scientist who came up with the the continental drift theory.
Who is Alfred Wegner?
300
Formed along faults, one side of the fault moves up while the other moves down.
What is a fault-block mountain?
300
A crack in the volcano where magma can escape.
What is a vent?
300
The fastest type of seismic waves. They can travel through solids, liquids, and gases.
What are P waves?
300
Large, gently sloped volcanoes that form from repeated, non-explosive eruptions of lava.
What is a Shield volcano?
400
The way the tectonic plates fit together.
What is a jigsaw puzzle?
400
Formed when magma pushes against the crust causing a bulge.
What is a dome mountain?
400
Where magma collects under the earth's surface.
What is a magma chamber?
400
The second fastest type of seismic waves. They cannot travel through materials that are completely liquid.
What are S waves?
400
The fragments of rock that are created by explosive volcanic eruptions.
What is pyroclastic material?
500
Where crustal plates float.
What is the upper layer of the mantle?
500
Tallest mountain in the world.
What is Mount Everest?
500
A volcano made up of alternating layers of lava and pyroclastic material.
What is a composite volcano?
500
Plates slide past each other, one plate slips along another, & when 2 plates come together.
What are 3 ways earthquakes can occur?
500
A small, steeply sloped volcano that forms from moderately explosive eruptions of pyroclastic material.
What is a Cinder Cone volcano?
