Explanation

The Grand Canyon was carved by the Colorado River over approximately 6 million years. The river's erosion exposed nearly 2 billion years of Earth's geological history. The Tigris is in Mesopotamia (Iraq), the Seine in France, and the Mississippi in the United States but did not create the Grand Canyon.
