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.
