Here's a breakdown of why:
* Geological Formation: The Rockies were formed by tectonic plate collisions, pushing up huge amounts of rock. This process created a vast, rugged landscape dominated by steep, rocky peaks, cliffs, and canyons.
* Visible Rock: Unlike some mountain ranges where vegetation covers most of the surface, the Rocky Mountains have extensive areas of exposed bedrock, visible to the eye. This makes the "rocky" aspect very apparent.
* Historical Names: Early explorers and settlers gave names based on what they observed. The rugged, rocky nature of the mountains naturally led to the name "Rocky Mountains."
So, the name "Rocky Mountains" is a simple and accurate description of the most prominent characteristic of this majestic range.
