What Is Earth's Crust Like?
ES0801  Summary

  !   Click the buttons below to compare the locations of volcanoes, earthquakes, and mountain belts.

5. How does the orientation (direction) of folded mountain belts compare with nearby zones of volcanoes and earthquakes?

6. What do chains of folded mountains tell you about Earth's crust?

Now think about what each of the three features you've examined indicates about Earth's crust. Consider what Earth’s crust is like in areas where all three of these features occur together. How are areas where these features occur different from areas without volcanoes, earthquakes and mountain belts? Examine the patterns on the map and visualize a mental model of Earth's crust.

7. From your examination of the data, describe your mental model of Earth's crust.

8. On the world map on your student answer sheet, outline the areas where Earth's internal heat escapes and solid rocks move against other solid rocks. Show folded mountain belts and draw arrows to indicate the direction in which pressure was applied to form them.
