200
Two evidences to support continental drift theory.
What is fossils, or puzzle pieces, or mountain formations, or rock formations, or glacial scarring.
200
Rigid, made mostly of bedrock, where we locate natural resources such as fossil fuels and water.
What is the upper mantle?
200
When one plate slips beneath another at a convergent boundary.
What is subduction?
200
Molten rock beneath earth's surface.

Name of the supercontinent.
What is Pangaea?
300
Thin, dense crust
What is oceanic crust?
300
Pushing toward each other - colliding
What is a convergent boundary? Bonus: 100 pts. Name a geologic feature that occurs at a convergent boundary where oceanic crust is colliding with continental crust.

Small, gently-sloped, non-violent volcanoes.
What are shield volcanoes.
400
A wave generated by the sudden movement of earth material beneath the ocean.

The plastic-like molten layer the plates "float" on.
What is the asthenosphere?
500
Earthquakes occur at these type of boundaries.
