Final answer:
Deserts typically experience hot temperatures during the day and cold temperatures at night due to low atmospheric water allowing rapid heating and cooling.
Step-by-step explanation:
The question asks which of the following best describes daily temperatures in deserts. The correct answer is that deserts are hot during the day and cold at night. This dramatic temperature change occurs due to the lack of atmospheric water, which allows rapid heating during the day and quick cooling at night. Subtropical hot deserts can have extreme soil surface temperatures above 60°C (140°F) during the day and temperatures approaching 0°C (32°F) at night. Furthermore, annual precipitation in these areas is very low, often less than 30 cm (12 in), which contributes to the aridity and temperature extremes.
