No, the Rockies formed as a consequence of the break-up of Pangaea.
Yes, the Rocky Mountains range is older than Pangaea. The formation of the Rockies began around 80 million years ago during the Laramide orogeny, while Pangaea existed around 335-175 million years ago before it started breaking apart.
No. They are younger. The earliest stages of the formation of the Alps began in the late Cretaceous, more than 100 million years after Pangaea broke up.
They are about the same age, actually. The Appalachians were formed as a result of the continental collisions that formed Pangaea.
Quite a bit younger. The Rockies are around 80 million years old; Pangaea formed about 300 million years ago and started to break up around 170 million years ago.
the Laurentian mountains are older than the rocky mountains because there is more plant life on the Laurentian mountains
The Appalachians are younger than Pangaea because they were formed during the process in which North America removed itself from Pangaea and into the west.
Quite a bit younger. The Rockies are around 80 million years old; Pangaea formed about 300 million years ago and started to break up around 170 million years ago.
The Appalachians are older than the Rockies, and they are weathered and smooth. The Rockies are jagged and rough. The Appalachian mountains are covered with trees and brush, and many of the Rocky mountains are bare rock.
The Appalachian Mountains are a great deal older than the Rockies.
The Appalachians are older than the Rockies, and they are weathered and smooth. The Rockies are jagged and rough. The Appalachian mountains are covered with trees and brush, and many of the Rocky mountains are bare rock.
The Himalayan mountains are older than the Appalachian mountains.
The Appalachians are much older than the Rockies and so they are more worn. The Appalachians are about 300 million years old, while the Rockies are about 65 million years old. As a result, the Appalachians are more worn. The Appalachians formed as a result of a collision between continents that formed the supercontinent Pangaea. The Rockies formed as an oceanic plate slid under the North American Plate at a shallow angle, dragging against the base of the crust.
