Plate Tectonics Review
The oldest rocks on the seafloor are located • Farthest away from the mid –ocean ridge.
This floats on the Asthenosphere • Lithosphere or a Tectonic Plate
An Oceanic Plate subducts at a Convergence with a continental plate, because. . . • It is denser than a continental plate.
Name the layers of the Earth. • Crust • Mantle • Inner Core • Outer Core
Name the 4 pieces of evidence Wegner used to support Continental Drift. • Puzzle pieces • Fossil clues • Rock clues • Climate clues
What 3 types of evidence do we have for seafloor spreading? • Age of rocks • Technology • Magnetic clues
What Technological evidence do we have for seafloor spreading? • Magnetometer • Sonar • Glomar Challenger
Tectonic plate theory is composed of these 2 theories • Wegner’s – Continental Drift • Hess’s – Seafloor spreading
