Plate Tectonics and People

In Lesson 1, we read a brief history of the basic research that led to the formulation of plate tectonics. In this lesson, research the life and scientific contributions of the scientist of your choice. The goal is to explain to your classmates how your scientist contributed to our modern view of the solid Earth.

I like the idea of starting this course with some exploration of the history of plate tectonics because it is such a young theory. In addition, if you probe a little farther you'll find that we knew a lot about the Earth before plate tectonics pulled it all together. I think it is pretty impressive to contemplate some of the observations made decades ago when scientists had nothing like the equipment capabilities for measurement and computation that we have available to us now.

I also think this is the perfect opportunity to get to know each other better by reading each other's work.

What will we learn in Lesson 2?

By the end of Lesson 2, you should be able to:

  • edit a Web page in Canvas
  • research the contribution to our knowledge of the solid Earth made by a particular scientist
  • explain the technological advances that improved geological observations of plate motions
  • describe the differences between the concepts of "continental drift," "sea-floor spreading," and "plate tectonics"
  • define and explain the following terminology: plate, lithosphere, asthenosphere, crust, mantle
