Where does the greatest daily temperature variation take place?

The greatest daily temperature variation typically occurs in desert regions, where clear skies and low humidity allow for rapid heating during the day and significant cooling at night. For example, locations like the Mojave Desert can experience temperature swings of over 50 degrees Fahrenheit (about 28 degrees Celsius) between day and night. This stark contrast is due to the lack of moisture in the air, which prevents heat retention after sunset.
