Core Content: SC-HS-2.3.8
Students will predict consequences of both rapid (volcanoes, earthquakes) and slow
(mountain building, plate movement) earth processes from evidence/data and justify
reasoning.
The earth’s surface is dynamic; earthquakes and volcanic eruptions can be observed on a
human time scale, but many processes, such as mountain building and plate movements,
take over hundred of millions of years.

Continental Drift and Plate Tectonics

Hook: The class will be grouped to work puzzles. The puzzle once complete will be
compared to the continents and the idea that they look like they could fit together.


Similarities and Differences: Students will be asked to determine how continental drift
and plate tectonics explain the placement of the items listed down the middle column.

Continental Drift            Placement of:                 Plate Tectonics

                             Volcanoes


                             Fossils


                             Seafloor spreading


                             Earthquakes



                             Mountain ranges

Continental Drift differences                               Plate Tectonics differences




Questions:

   1. Are continental drift and plate tectonics more alike or different? Explain your
      answer.




   2. What do you suspect to be the major informational changes from the idea of
      continental drift to the idea of plate tectonics?




   3. Plate tectonics allows us to look at the plate boundaries individually to see the
      direction of the movement. Describe the differences in convergent, transform,
      and divergent boundaries.
Application:

Using all of these supplies- create a model representing the movement of the plates. Be
sure to show how the movements of the plates create volcanoes, earthquakes, and
seafloor spreading.
