How did the river carve the Grand Canyon?
Sixty million years ago, the Rocky Mountains and the entire Colorado Plateau, which the Grand Canyon is part of, rose up from tectonic activity. By around 6 million years ago, waters rushing off the Rockies had formed the mighty Colorado River. As the plateau rose, the river cut into it, carving the canyon over time.
Why doesn’t the Mississippi river carve a canyon?
Mississippi is an old river whose rock eroded away long ago and it’s now mostly on an alluvial flood plains: all sediment/soil and no rock to eat through. Because the Mississippi doesn’t drop nearly as far in elevation, it can’t do as much work as the Colorado in carving a long, deep canyon.
What happened to the river in the Grand Canyon?
The base level and course of the Colorado River (or its ancestral equivalent) changed 5.3 million years ago when the Gulf of California opened and lowered the river’s base level (its lowest point). This increased the rate of erosion and cut nearly all of the Grand Canyon’s current depth by 1.2 million years ago.

Do rivers form canyons?
The movement of rivers, the processes of weathering and erosion, and tectonic activity create canyons. The most familiar type of canyon is probably the river canyon. The water pressure of a river can cut deep into a river bed. Sediments from the river bed are carried downstream, creating a deep, narrow channel.
