Where did mountains that aren't at plate boundaries today, like the Appalachians and Urals, come from?
Lesson Objectives...
Construct a scientific explanation based on evidence from a model that colliding tectonic plates caused the formation of the Appalachian Mountains and the Ural Mountains at time and spatial scales that are not observable.

Now focus on the Appalachian Mountains. Type Asheville, North Carolina in the search window to place a pin on the area you are focusing on. Go back to about 200 mya to 250 mya and move further back in time. What caused the Appalachian Mountains to form?
Formation of the Urals...

Now focus on the Ural Mountains. It is close to Yekaterinburg, Russia. Type Yekaterinburg, Russia in the search window to place a pin on the area you are focusing on. Now go back in time. What caused the Ural Mountains to form?
Formation of the Himalayan Mountains...
Formation of the Himalayan Mountains...
Now focus on the Himalayan Mountains. It is close to Kathmandu the capital city of Nepal. Type Kathmandu, Nepal in the search window to place a pin on the area you are focusing on. Now go back in time. What caused the Himalayan Mountains to form?

What we figured out this lesson...
- The Appalachian Mountains, formed 470 million years ago, and the Ural Mountains, formed more than 300 million years ago, were both created in the same way that other mountains were formed--through plate collisions. (Lesson 12)
- Plate interactions cannot explain why the Appalachians are decreasing in elevation or why the Ural Mountains are neither increasing or decreasing in elevation. (Lesson 12)
