The name for Wegener's supercontinent
What is Pangaea?
The person who proposed the idea of Continental Drift
Who is Wegener?

What is Noah's flood?
In addition to fossils, the two other types of evidence for Continental Drift
What are landforms and climate?

Transfer of heat by movement of fluids
What is convection?
This is found in the mantle. It is soft and allows the lithosphere to "float" on top of it.
What is the asthenosphere?
