As you can see from this map, the Ural Mountains exhibit a north-south orientation through Eurasia. They are about the same age as the Appalachian mountains of eastern North America
How does the theory of plate tectonics explain the existence of this mountain belt in the interior of an expansive continental landmass? Compare and contrast the Ural and Appalachian situations, given their similar age.
What will be an ideal response?
Answer: It must be an old continent—continent collisional mountain belt, the way the Himalayas are today forming where India and Eurasia are colliding. Here, ancestral "Europe" and "Asia" collided, and stayed stuck together. The Appalachians formed in a similar collision during the assembly of Pangaea, but there the mountain belt was also where the crust broke when rifting opened the Atlantic.
