Title:	Chemistry: Ten things we need to know about ice and snow.
Authors:	Bartels-Rausch, Thorsten
Source:	Nature. 2/7/2013, Vol. 494 Issue 7435, p27-29. 3p. 2 Color Photographs.
Subjects:	Ice, Snow, Hydrogen bonding, Molecular association, Evaporites
Abstract:	The article focuses on the molecular behavior of ice and snow. Crystals of made up of water molecules, which are held in a regular tetrahedral arrangement by hydrogen bonding. Amorphous ice might form on comets when water condenses at extremely low temperatures. Water molecules in the surface layers of ice and snow are evaporating and re-freezing continually.
