How Are Mountains Related to Plate Tectonics?
ES1101  Appalachian Mountain Belt

The Appalachian Mountain belt stretches along most of the east coast of North America. This mountain belt is subdued compared to the Andes and Himalayan mountains—the highest point in the Appalachian Mountain belt is Mount Mitchell, in Tennessee. Its elevation is 2037 meters above sea level (not much more than 1 mile). The southern part of the Appalachians contains spectacular folded mountains. The region has no active volcanoes, and earthquakes are very rare.

5. On the map of North America on your student answer sheet, sketch in the location of the Appalachian Mountain belt, and record its length and width.

Look at a map of global plate boundaries to find the plate boundary nearest the Appalachian Mountain belt (page 713 in your textbook).

6. How do you think these mountains formed? What do you notice about the Appalachian Mountain belt and current plate boundaries?
