What was the Grand Canyon before it became 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. After the top layers of rock (green) eroded away, the Colorado River grew powerful and began to cut its way through the ancient rock, leaving the stunning canyon we see today.
When did the Grand Canyon become a canyon?
5 to 6 million years ago
Scientists estimate the canyon may have formed 5 to 6 million years ago when the Colorado River began to cut a channel through layers of rock.
How old is Grand Canyon?

Yarlung Tsangpo Grand Canyon
Largest canyons

Why is the Grand Canyon hotter at the bottom?
As air sinks down into a lower elevation, it gets compressed, compressed air releases heat as energy. This caused the air mass to become even warmer. “This is why you can see temperatures in the 90’s at the top of the Grand Canyon but temperatures 20-30 degrees hotter at the bottom of the canyon,” Brink says.
