Which statement best describes the climate of a desert region?

The climate of a desert region is characterized by low precipitation and significant temperature fluctuations. Deserts typically receive less than 10 inches of rainfall annually, making moisture scarcity a defining feature. This lack of precipitation contributes to the arid conditions found in such regions.

In addition to low moisture, deserts often experience large temperature fluctuations between day and night. During the day, temperatures can soar due to intense solar radiation, while nighttime temperatures can drop significantly as heat escapes the surface. This variation creates dramatic temperature differences, a hallmark of desert climates.

Understanding this combination of low precipitation and considerable temperature variation is crucial in distinguishing desert climates from other types, where different moisture levels and temperature ranges would prevail throughout the year.
