While other agents like wind and ice have played a role, the Colorado River and its tributaries have carved the canyon over millions of years.
Here's how it works:
* Running water: The Colorado River flows through the canyon, constantly eroding the rock with its force.
* Abrasion: As the river carries sediment, it grinds against the canyon walls, wearing them down.
* Chemical weathering: Water also dissolves some of the rock, further weakening it.
The Grand Canyon is a testament to the immense power of water erosion over long periods.
