The Grand Canyon.
- Erosion from ice, water and wind are widely believed to be the main causes of the formation of the Grand Canyon.
- The Colorado River is credited with much of the work that created the canyon, although it’s highly unlikely that the river alone created the massive canyon we see today.
- The Grand Canyon is mostly made up of desert.
The definition of the Grand Canyon is a series of deep gorges in Northwest Arizona which contain the Colorado River.
