Test Description: Select Vocabulary from the Plate Tectonic Unit
Instructions: Answer all questions to get your test result.
1) What is the correct definition of: Plate Tectonics?
A
The theory that the earth is broken into plates and are in motion due to convection currents in the asthenosphere

term for the super continent which contained all the plates together

The process by which new oceanic crust forms as magma rises towards the surface and solidifies at divergent boundaries.
D
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present location
