Crystalline structure of snow
Webgeometric shape. The shape of a crystal results from the way the atoms or molecules of a mineral come together as the mineral is forming. So, each mineral has its own crystal shape. This solid body has a characteristic internal structure and is enclosed by symmetrically arranged plane surfaces, intersecting at definite and characteristic angles. WebSnow is made of ice crystals, and up close the individual crystals look clear, like glass. A large pile of snow crystals looks white for the same reason a pile of crushed glass looks …
