Continental Drift/ Plate Tectonics
Transcript of Continental Drift/ Plate Tectonics
1912: Wegener proposed a hypothesis of continental drift. Continental Drift Continental Drift: the idea that a past supercontinent split apart into pieces which drifted over time to their present location. Review
Hypothesis: Educated guess
Theory: A well-established explanation for scientific data. Theories typically cannot be proven but are established if multiple scientists have tested them. Vocabulary Plate Tectonics Vocabulary
Plate Tectonics: The theory that the Earth's surface is made up of separate, rigid plates that move slowly across the mantle.
Subduction: A process that occurs when tectonic plates converge on and one plate sinks or slides under the other.
Mid-Ocean Ridge: A vast, underwater mountain chain that has been built up by the addition of new rock from below two tectonic plates moving apart under the oceans. What is a hypothesis??
What is a theory?? Using your talking chips, discuss what other reasons could Alfred Wegener have researched that would have helped him to form his hypothesis about the Continental Drift? Ticket out the door Discuss in your groups why the geologists were so skeptical of Alfred Wegener's theory when it was proposed in 1910?
Each student write a different question that the geologists may have asked Alfred Wegener about the Continental Drift???
