Plate Tectonics - Part 1; Continental Drift

This web cast looks at Alfred Wegener's theory of continental drift, which led to the current theory of plate tectonics

What you Need to Know...

Be able to explain the hypothesis of continental drift
Be able to list and describe the evidence for this hypothesis
What was the main objections to Wegener's hypothesis?
What is Pangaea and how is it related to continental drift?

Earth 100 Million Years From Now...

Earth's landmasses were not always what they are today. Continents formed as Earth's crustal plates shifted and collided over long periods of time. This video shows how today's continents are thought to have evolved over the last 600 million years, and where they'll end up in the next 100 million years.

Part 3 - Sea Floor Spreading

This lecture looks at the divergent boundary known as a spreading center. This boundary can form new sea floor and spread continents apart. Evidence that supports sea floor spreading is also presented.

Movie: San Andreas

After watching the movie, San Andreas, go to the following web sites (click the links below) and, point by point, explain if what you saw could happen or what is scientifically wrong with that part of the plot.

What's Scientifically Wrong with the movie San Andreas?

Could San Andreas Actually Happen?
