The Dramatic Landscapes of the American West
In The Dramatic Landscapes of the American West, narrator Sir David Attenborough explores the desert of the American West as a 10-month drought is ended by an intense thunderstorm. As millions of tons of water are dumped in under an hour, raging rivers form. Over millions of years, raging waters like these have carved slot canyons and shaped a beautiful landscape. This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.
Lesson Express
Q: How does rain come to the American West, according to the video?
A: After months of drought, the rain comes all at once, pouring down tons of water in under an hour.
Q: Is it the water alone that carves the channels through solid rock?

Q: Is this type of rainfall helpful? Harmful?
A: Although the rain brings needed moisture and carves beautiful landscapes, it can be harmful if people or animals can’t get to safety in time.
