Final answer:
The physical features of the Rocky Mountain region include mountains, plateaus, and canyons.
Step-by-step explanation:
The physical features of the Rocky Mountain region include:
- Mountains: The Rocky Mountains are an immense range that stretch from New Mexico to Northern Canada. They were formed 80 million to 55 million years ago and have been glaciated and eroded, giving them rounded peaks.
- Plateaus: The Colorado Plateau and the Columbia Plateau are two prominent plateaus in the region. The Colorado Plateau is composed of horizontal Paleozoic and Mesozoic sedimentary rocks, while the Columbia Plateau is a large igneous province dominated by volcanic rocks.
- Canyons: The region is known for its immense canyons, such as the Grand Canyon in Arizona. These canyons were formed during the Laramide Orogeny when the area experienced dramatic uplift.
