Answer:

The natural landmark formed about five to six million years as erosion from the Colorado River cut a deep channel through layers of rock. The Grand Canyon contains some of the oldest exposed rock on Earth. The mile-high walls reveal a cross section of Earth's crust going back nearly two billion years.
