The correct response is:
D Folded mountains occur when two plates of the Earth's crust push against each other.
Folded mountains, like the Appalachian Mountains, form as a result of tectonic forces that compress and fold the Earth's crust.
The Appalachian Mountains are approximately 480 million years old, making them the oldest mountains in North America. The Appalachian Mountains are folded mountains that were once as high as 20,000 feet. Now they reach to about 3,000 feet. How did these mountains form?
