Plate Tectonics Vocabulary 8. Continental Drift = the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
Title: Sep 10 ­ 3:00 PM (8 of 19)
Plate Tectonics Vocabulary 9. Sea­floor Spreading = the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.
