Earth Science - Evidence and Models of Plate Tectonics

Explore the compelling evidence and models supporting plate tectonics in this 35-minute Earth Science lecture. Delve into the breakup of Pangaea, future plate movements, and various forms of evidence including ocean drilling, mantle plumes, hot spots, paleomagnetism, polar wandering, and magnetic reversals. Examine the forces driving plate motion and compare the whole-mantle convection and layer cake models. Enhance your understanding with a magnetic field demonstration, providing visual insight into Earth's dynamic processes.
