These things sometimes contain small, short features called zibars. Gilgai patterns often form on playas in these things. They often produce fields of yardangs. These things often produce calcrete, gypcrete, or silcrete. The creation of these things often produces striped vegetation patterns called "tiger bush." The history of these things can be studied by examining (*) ventifacts. These things have thick duricrusts. These regions are often classified as xeric and are the most common terrestrial biomes. The creation of these areas can be slowed by digging contour trenches, fixing seifs and barchans, or planting "shelterbelts" of plants. Lake Chad has shrunk drastically due to the spread of these areas. For 10 points, name these arid regions exemplified by the Sahara.
