Activity: World Deserts Note to teachers/sponsors: The activities that follow are suggestions. You are encouraged to adapt them as you need to, so they are useful to the ages and abilities of your group. Feel free to pick and choose from these activities. Also, use them as springboards to other activities that fit the interests of your students. You may also want to incorporate a field study experience, if applicable. Introduction Deserts are regions of the Earth s surface that receive less than 10 inches (25 centimeters) of precipitation a year. Evaporation rates are higher than precipitation in deserts, leading to the arid conditions. Not all deserts are hot. Temperature is generally not a factor in defining a desert. Some deserts are hot, with temperatures exceeding 100 degrees F. Other deserts are have cold winters or are cool all year. Deserts cover about 20 percent of the Earth s surface. Deserts are divided into five types: subtropical coastal rain shadow interior polar National Council for Geographic Education Page 2 of 6
Subtropical deserts lie along the Tropic of Cancer and the Tropic of Capricorn between 15 and 30 degrees north and south of the Equator. Hot moist air rises near the Equator. As it rises, it cools and drops heavy rains in tropical areas. Now cooler and drier, this air sinks and warms in the area of the Tropics of Cancer and Capricorn. This creates the subtropical deserts of North Africa and Australia. The Sahara Desert is a subtropical desert. Coastal deserts are caused by cold ocean currents that lie just offshore the west coasts of some continents, particularly in the Southern Hemisphere. These deserts are often accompanied by fog, but receive very little rainfall. The Namib Desert in Africa is a coastal desert. Rain shadow deserts are found on the leeward sides of mountain ranges. Leeward slopes are those that face away from the prevailing winds. Precipitation falls along the windward side of the mountains. The air that descends the leeward side has little moisture left, creating arid conditions. Patagonia, in Argentina is an example. Interior deserts are located deep in the interiors of large continents, far from oceans or seas. Air reaching these areas has long since dropped its moisture, creating dry conditions. The Gobi Desert in Asia is an interior desert. Polar deserts are located in polar regions. Antarctica and parts of the polar tundra of North America and Asia are polar deserts. Although covered with compacted ice and snow, these areas receive less than 10 inches of precipitation annually, and by definition, are deserts.

They can work in teams or individually. The Student Activity Sheet can be found with the fourth month activity on the NCGE Geography Club website. Activity: Mapping Desert Regions Have students use an outline map of the world to locate major deserts. Have them label the map with the names of the deserts. If desired, the deserts can be classified by their type. National Council for Geographic Education Page 3 of 6
Link to world outline map: http://www.nationalgeographic.com/xpeditions/atlas/ Investigate: Water sources in deserts Although deserts receive little rainfall, there is water present. Rivers, oases, and groundwater are water sources in some deserts. Rivers that flow from areas with adequate precipitation to desert regions are called exotic rivers. Exotic rivers provide water for plants and wildlife in deserts. They support human populations dating back to early civilizations. Have students identify major rivers that flow through deserts. Some suggested rivers are: Colorado River and its tributaries, Nile River, Tigris River, Euphrates River, Jordan River, and the Indus River. Which of these rivers were cradles of civilizations? What role do these rivers play in the development of desert regions? Investigate: Desert Cities Deserts tend to be sparsely populated regions. There are, however, areas of large concentrated populations in desert regions. Students can identify, locate, and learn about some major desert cities. Some cities to investigate are: Phoenix, Arizona, Las Vegas, Nevada, and cities of the U.S. Southwest Riyadh, Saudi Arabia and other cities of the Middle East Cairo, Egypt Timbuktu, Mali and other cities of the Sahara 1. What are the sources of water for these cities? 2. How do the large cities of the U.S. Southwest have adequate water supplies to meet the demands of the large and growing populations? 3. What are some environmental issues related to water use in the U.S. Southwest? Investigate: Desert Words Can you identify these terms? What words related to deserts can you add to the list? arid erg rain shadow arroyo exotic river reg badlands hoodoos sand dunes canyon Joshua tree saguaro desertification oasis wadi eolian erosion playas xerophitic National Council for Geographic Education Page 4 of 6
III. Geo-Questions The Middle East is largely a desert domain. Test your geographic knowledge of the Middle East by answering these questions. 1.
