PLATE TECTONICS Pre-Lab Exercise

In the lab activity, you will investigate maps of earthquakes and volcanoes, and relate them to the movements of the plates and major geographic features of the ocean floor.

For this pre-lab activity, watch and listen to the three voice-over videos below. Each video explores some important concepts of plate tectonics. Use the information to answer the pre-lab questions.

Note: You can turn CAPTIONS on or off by clicking “CC” at the bottom right of the video screens. Also, you can view the videos at higher resolution by choosing a better quality option from the menu at the bottom right of the screen.
