Science: from High Tide in Tucson
Desert Climates (p. 134)
When you think of a desert, Antarctica probably doesn't come to mind first. Deserts are classified into three types. Low-latitude deserts, such as the Sahara of North Africa, lie near the equator, and are hot and dry all year long. In mid-latitude deserts, like the one described in "High Tide in Tucson," the climate varies from light frost in winter to extreme heat in summer. High-latitude deserts lie near the North and South Poles and include the frozen deserts of Greenland and Antarctica. Learn more about desert climates by clicking through the links below.
