Snow
Snow is a form of frozen water. / It contains many groups of tiny ice particles called snow crystals. / These crystals grow from water particles in cold clouds. / They usually grow around a piece of dust. / All snow crystals have six sides, but they grow in different shapes. / The shape depends mainly on the temperature and water levels in the air. /
Snow crystals grow in one of two designs—platelike and columnar. / Platelike crystals are flat. / They form when the air temperature is about fifteen degrees below zero Celsius. / Columnar snow crystals look like sticks of ice. / They form when the temperature is about five degrees below zero Celsius. /
The shape of a snow crystal may change from one form to another / as the crystal passes through levels of air with different temperatures. / When melting snow crystals or raindrops fall through very cold air, / they freeze to form small particles of ice, called sleet. /
解析
雪
雪是水的固体形态,是由许多微小的冰晶聚合而成的固态降水。这些冰晶都是由寒冷云层中的水微粒围绕着尘埃而形成的。所有的冰晶都有6个角,但却能形成不同的形状。冰晶有片状和柱状之分。形成什么样的形状主要取决于温度和空气中的含水量。
