  • Thermal imagery can be used to show the diurnal range of temperature in the hot deserts. The temperature of the desert drops to below freezing during the night. In the daytime the surfaces facing the sun can be 30 degrees hotter than those facing away from the sun. Animals in the desert adapt to the climate by burying themselves in the sand or changing colour to reflect the heat.
