Question

How were the Appalachain Mountains formed?

Answer 1

The Appalachian Mountains were most likely formed by plate collision.

Explanation:

The main ways that mountains are formed are glaciers, volcanic activity, or plate collision.

Glaciers are very unlikely since they often form hills but seldom mountains and since the Appalachian Mountains extend down to Alabama and Georgia.

Volcanoes are almost always located along the edge of a tectonic plate. They are often accompanied by earthquakes. The Appalachian Mountains have very few earthquakes and are not along a plate boundary.

Plate collision, although not happening today in the Appalachian Mountains is believed to have occurred during the breakup of Pangaea. This would have caused mountains very similar to the Appalachians.
