On earth we have some cold deserts, where year round cold and unmelting snow create environments where life forms face formidable challenges. This environment is found on the peaks of high mountains and near the poles. Parts of the Antarctic are cold deserts, and the inland mountains of Greenland are deeply buried in snowfields. Although scientists have found some bacteria living underneath glaciers, life forms in this environment are generally just visitors. Parts of these icy environments are in motion.
Glaciers slowly flow downhill or toward the oceans, carving out the landscape as they go.
As glaciers move, sometimes the ice cracks and deep crevasses are formed. If you stand near a glacier you can hear creaking and cracking sounds as the ice moves along. Cold air does not hold much water vapor. The driest deserts on earth are the dry, cold deserts in Antarctica. Some places in Antarctica haven't received any rain for 4 million years, although they do receive water from the runoff from nearby mountains when some of the snow melts.
