a hell storm
Dust swirls are common in hot deserts. They look like small tornadoes, but they start on the ground, not the sky. When areas of land get too hot, the hot air above them begins to rise and swirl. This rotating column of hot air collects dust and dirt. These rotating pillars of earth can reach hundreds of feet into the air.

hot and cold deserts
The largest hot desert in the world is the Sahara at 9 million square kilometers (3.5 million sq mi). However, it is not the hottest place on earth. This award belongs to Death Valley in California's Mojave Desert. The highest temperature on earth was recorded there: 56.7 C (134.1 F).

The largest polar desert is Antarctica at 13 million square kilometers (5 million sq mi). Antarctica has the lowest officially recorded temperature on Earth: -89.2 C (-128.6 F) recorded on July 21, 1983.

rose from the ashes
The desert city of Phoenix, Arizona is named for the mythical desert bird that cremates only to be reborn and rises from its own ashes. The city of Phoenix was built on the ruins of canals built by the Hohokam people between 500 and 1450 AD. The Hohokam used the canals to water their crops. Modern residents also rely on an extensive canal system for irrigation.
