Evidence for Continental Drift –

fossils

climate

rocks
What causes the plates to move?
Convection currents
What is sea-floor spreading?
The process by which molten material adds new oceanic crust to the ocean floor
____Oceanic____ crust subducts under ______Continental______ crust because it is
more dense.
How are depth in the earth and density of earth’s layers related?
As you go deeper into the Earth the layers’ density increases. (as depth increases than
density increases)
