The Grand Canyon

The Grand Canyon

A Canyon So Grand The Grand Canyon is so big that we can see it from space. It became a national park in 1919.

A national park is an area of protected land.

Formation The Colorado River made the Grand Canyon through erosion. Erosion happens when bits of the ground are worn away. The river ran over the earth, and after many years, a canyon was made.

The Grand Canyon is striped with colors. The stripes are layers of sediment that built up on top of each other. They show how Earth has changed over time.

Exploration Native Americans went to the Grand Canyon first. People can still see some of their homes there.
