Books recommended by SearchIt!Science:
Snow Amazing: Cool Facts and Warm Tales Jane Drake, Ann Love
Published by Tundra Books, 2004.
If you want to know anything and everything about snow, turn to this playfully illustrated book. Its short chapters cover dozens of snowy topics: how snow crystals develop, spring thaws, how filmmakers film snow, snow prints, avalanches, snowbirds, and more. Along with weather information, stories of snowy expeditions, and information about snow-dwelling plants and animals, the book offers wintry folktales from around the world.

sublimation The process of changing from a solid to a gas, or from a gas to a solid, without turning into a liquid first. Frost sometimes evaporates by sublimation.
Solid carbon dioxide, known as dry ice, seems to give off smoke at room temperature. This "smoke" is actually the solid carbon dioxide turning directly into a gas in the process known as sublimation. Dry ice is useful for packing certain materials that need to stay cold, since it doesn't melt and get everything wet.
