source of water in a desert, but it falls very rarely. When it rains, dormant seeds wake up and form desert blooms. Soils and Geomorphology in the Basin and Range Area of Southern New Mexico, Guidebook to the Desert Project. The reasons for this separation are not well understood, but perhaps the influence of soil texture on racism in sports today essay the infiltration and availability of water affect the two species in different ways. With little vegetation to anchor it, the thin topsoil quickly eroded.

You may also detect them by changes in texture and other characteristics. Sand lizards, native to the deserts of Europe and Asia, are nicknamed dancing lizards because of the way they quickly lift one leg at a time off the hot desert sand. Subterranean termites transport a tremendous amount of relatively deep soil materials to the surface when they construct their mud-covered tunnels on the soil surfaces and on the cellulose-containing foods they consume. Many desert animals have developed ingenious ways of getting the water they need. In a detailed study that spanned a decade in the northern Chihuahaun Desert near Las Cruces, New Mexico, dust traps positioned about thirty-five inches (90 cm) above the soil surface collected an average of more than one ounce (23 g) of dust per square meter. These kinds of pavements exist in a limited number of locations in the Sonoran Desert region, but are less common by far than pavements that developed on coarse, rocky parent materials as described previously. Desertification is not new. Wind builds dunes that rise as high as 180 meters (590 feet). These desert pavements are rare or absent in the moister parts of the Sonoran Desert, but become increasingly pronounced in the driest parts (see the photo below). For example, in the Mohave Desert, desert tortoises apparently require soils that are loose enough to be excavated, but firm enough so that the burrows will not collapse. Animals can profoundly affect characteristics of desert soils. Intaglios of the Sonoran Desert are frequently ten yards (10 m) or so long.
