The person who developed the theory of continental drift.
Who is Alfred Wegener?
100
The top layer of crust and top portion of mantle
What is the lithosphere?
100
The area around the Pacific Ocean where volcanoes and earthquakes occur.
What is the Ring of Fire?
100
A place where magma and other debris come out of the earth.
What is a volcano?
200
Where plate boundaries move away from each other
What is a divergent boundary?
200
The cause for sea floor spreading and where it occurs
What is new magma coming up at a divergent boundary (or Mid-Oceanic ridge)?
200
Name for energy from the earth
What is geothermal?
200
The place in the earth where from which the earthquake is generated
What is the focus?
200
The type of volcano composed of slow lava flows.
What is a shield volcano?
300
Where plates grind as they slide past each other.
What is a Transform boundary?
300
The mechanism that pushes the tectonic plates around.
What is mantle convection
300
The "pieces" of the crust
What are the tectonic plates?
300
The place on the surface of the earth directly over the focus.
What is epicenter?
300
The type of volcano that is explosive.
What is a cinder cone volcano?
400
These formed when two continental plates converge and rock "scrunched."
What are folded mountains?
400
The theory that formed from Continental Drift.
What is the theory of Plate Tectonics?
400
How scientists determined the composition of the earth.
What is by tracking the speed of seismic waves and explosions?
400
Measures the magnitude of an Earthquake.
What is the Ricther Scale?
400
The type of volcano that has altering explosive and then calm lava flows.
What is a composite volcano?
500
When an ocean crust slides underneath the continental crust and what forms nearby?
What is a subduction zone and volcanoes (volcanic arc)?
500
Fit of the continents, fossils, climate, and mountains?
What is evidence for Continental Drift?
500
The plastic like layer that is where the convection occurs.
What the asnthenosphere?
500
The two types of seismic waves and one way they are different from one another
What is primary and secondary waves? What is primary waves are faster OR primary waves compress the ground back and forth and secondary waves make the ground go up and down?
500
A place in the middle of a tectonic plate that produces volcanoes like Hawaii and Yellowstone.
