Science, Continental - Continental where 100 million years ago where these two Earth crust collided together and after a while it started building up, and eventually became a mountain. The Rocky Mountains formed west to east, as based on geological evidence. The Appalachian Mountains formed from east to west, again based on geological evidence. The Appalachian Mountains are much older than The Rocky Mountains. The Rocky Mountains contains rock sediments proven to be from The Appalachian Mountains.

The mountains were made by the Yellowstone volcano about 100000 years ago
Where is the rocky mountains located and how do they form?

When those plates crashed together, they forced the earth's crust to go up, and over time the plates were pushed together so much, it forced them really high and they formed the Rocky mountains.

Are the Rocky Mountains located in Canada or the US?
No, the Rockies are relatively young, as mountains go. They were formed about 70 million years ago. Some think the oldest are the Appalachians, which formed 460 millionyears ago, but one range is much older. This would be the Saint Francois Mountains of southeastern Missouri, a part of the Ozark region. They were formed in Precambrian time, 1.4BILLION years ago.
Is the Cascade Mountain Range older than the Rocky Mountains?
No. That honor would go to the Porcupine Mountains in Northwest Michigan. They were formed 2 billion years ago. It was formerly and erroneously thought that the Saint Francois Mountains of Southeast Missouri (formed 1.4 Billion Years ago). The Appalachian Mountains were formed only 460 million years ago..
