How are the Rocky Mountains different from the Appalachian Mountains?

• The Rocky Mountains are much higher and older than the Appalachian Mountains.
• The Rocky Mountains have been worn down by erosion and glaciation; the Appalachian have not been worn down.
• The Appalachian Mountains are older and more eroded than the Rocky Mountains.
• Both mountain ranges are of the same age and elevation, but the Rocky Mountains have been cut by wind and water erosion.

What is the mechanical and chemical processes that change Earth’s surface over time? - the breaking

The boundary between two plates that move toward each other is called a
