The theory that describes the formation, movements, and interactions of plates is called plate _?_.
The hypothesis that says that the continents have move or drifted from one place to another.
shape of the continents and fossil evidence
Early evidence that backed Wegener's hypothesis of continental drift
A reptile that lived 270 million years ao, and its remains are found only in parts of South America and Africa.
A long of chain of voclanic mountains on the ocean floor with a deep central valley.
Information about magnetic reversals stored in bands of igneous rocks on the ocean floor that lie on both sides of a mid-ocean ridge
evidence that new rock is being formed as plates move apart
The rocks along mid-ocean ridges are unusually warm. The amount of heat leaving the rocks decreases as you move further from the mid-ocean ridges.
The boundary that forms when two continents collide and are welded into a single, larger continent.
The older, denser lithosphere slides away from the ridge and helps push the plates apart.
Sediments from the ocean floor that is scrapped off and left behind as an oceanic plate plunges under a continental plate at a subduction boundary
A source of growth material that consists of the sediments that are deposited by rivers that flow off of the continents
A large block of lithospheric plate that has been moved, often over a distance of thousands of kilometers, and attached to the edge of a continent.
