How was the Grand Canyon created

How was the Grand Canyon created

The Grand Canyon was created by a river on a plateau. A plateau is a flat piece of land. For millions of years, just even before the humans arrived, the river started to go down into the deep plateau and slowly carved the Grand Canon. Scientists believe that it took 3,000,000 yrs – 7,000,000yrs to carve. By the way, if you’ve been to the Grand Canyon, can you post a comment on my blog and I would like to read them. Thank You!
