20 POINTSSS!! How did the rock of the Rocky Mountains form?

It's only 5 but whatever, they formed through millions of years of erosion

The Rocky Mountains formed 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began sliding underneath the North American plate.

I hope this helps! -connie :}
