Scientists defined deserts as areas of land where there are lessthan ten inches of rainfalls per year and there are few plants. 26 Precipitation is almost always frozen in theform of ice or snow. 27 So these regions are considered deserts and given the special label “cold deserts.”The low temperature there ranges from 10 to 50°F. in summer and from -50 to 10°F. in winter.28 As with cold deserts, there is usually little water available for plant growth. But contrary to whatmany people think, hot deserts are not lifeless wastelands. 29 These species have learned to adapt tothe lack of water and harsh temperatures. Also, they are not necessarily made up of endless shifting sanddunes. 30 Some deserts have steep, rocky mountains, while others are flat.
