This colorful book describes the geological makeup and history of the Kalahari Desert in Africa. Covering most of Botswana, as well as portions of Namibia and South Africa, the Kalahari is not a true desert because it receives more than ten inches (250 mm) of rain each year. But the rain drains and evaporates quickly leaving no water on the surface of the red sand. Readers will learn about the variety of habitats in this vast desert system that support many different kinds of plants and animals such as springboks, giraffes, elephants, and zebras. Special sections also describe the Kalahari's natural resources, indigenous people, and the unique problems facing this region.
This intriguing book describes the geological makeup and history of the Gobi Desert in Mongolia and China. Temperatures can get very cold and frost and snow are not unusual. Readers will learn about the variety of habitats in this vast desert system that support many different kinds of plants and animals such as camels, snow leopards, and bears. The Gobi Desert is also where the first dinosaur egg fossils were found.
