1. The Big One - Assessment
- Collect the handouts.
- Ask students to explain what causes an earthquake. Include both a short paragraph and a labeled picture.
- Add information about earthquake depth to the student tables and the class map. The deepest earthquakes tend to take place on or near subduction zones.
- See if the location of volcanoes also matches the plate boundary lines. Add data about the mid-ocean ridges and identify plate boundary lines. See the Plate Patterns activity for details.
- Look at the earthquakes that didn’t line up on a plate boundary. What is happening there? Investigate the causes of earthquakes that didn’t occur on a plate boundary.
- Play with the “This Dynamic Planet” map which allows you to select certain types of data to display on a dynamically generated map. Some of the data types you can select are volcanoes, earthquakes of different magnitudes, impact craters, plate boundaries, latitude/longitude grids and more.
