What is granite?
200
The scientist who proposed the theory of continental drift
Who is Alfred Wegener?
200
Mountains are formed from this type of boundary movement
What is convergent boundary?
200
This is the transfer of energy through space
What is radiation?
200
The lithosphere includes all of this and part of the mantle
What is the crust?
300
This is a break in the Earth's crust where rocks have slipped past each other
What is a fault?
300
Scientists rejected Wegener's theory because he couldn't do this
What is explain what pushes or pulls continents?
300

This is the crust that goes below the other when continental and oceanic crusts converge

What is the oceanic crust?

300

The scientist who discovered sea floor spreading.

What is crust, mantle, outer core, inner core?
400
This part of the mantle can bend like plastic

400

This is what scientists now know about the mantle that would have answered the scientists who rejected Wegener's theory.

400

The process by which oceanic crust goes underneath continental crust in a convergent boundary.

500

This is what happens when the divergent boundaries underwater have volcanoes that are making new crust.
