Earth Science - Weather - Learning Points. Deserts are the driest regions on Earth. Deserts can be stony or sandy, hot or cold. Deserts are formed in extremely arid atmospheres, e.g. at the equator where rainfall is scarce, in the shadow of mountain ranges. Polar deserts exist in the Antarctic and Arctic, where water is locked in permafrost and ice and there is little within the air. A Twig Context Film.
