It is homogeneous (of one material), formed inorganically, and has an ordered atomic structure.

Ice is naturally occurring, given a temperature below 0 ☌ (32 ☏). A mineral is a naturally occurring homogeneous solid, inorganically formed, with a definite chemical composition and an ordered atomic arrangement. When the balls of ice become too heavy for the updrafts to continue supporting them, they fall as hailstones.īecause snow is composed of frozen water, or ice, it can also be classified as a mineral. Drops of supercooled water hit the graupel and freeze to it, causing the graupel to grow. Hailstones form when upward moving air in a thunderstorm, or updrafts, prevent pieces of graupel from falling.

Hail tends to be larger than sleet, and is usually generated during thunderstorms, which happen more often in spring and summer than in winter. One form of precipitation, hail, while frozen, is not considered snow.In some parts of the United States, the term sleet can refer to a mixture of ice pellets and freezing rain. Official weather observations may list sleet as ice pellets. These small, translucent balls of ice are usually smaller than 0.76 centimeters (0.30 inches) in diameter. Sleet is composed of drops of rain or drizzle that freeze into ice as they fall, and is sometimes called a wintery mix of rain and snow.The cloud droplets then freeze to the crystals, forming a lumpy mass. They form as ice crystals fall through supercooled cloud droplets, which are below freezing but remain a liquid. Snow pellets, or graupel, are opaque ice particles in the atmosphere.Snowflakes are clusters of ice crystals that fall from a cloud.Exchange for Observations and Local Knowledge of the Arctic (ELOKA)Ī person crosses the street in Frome, England, during a snowstorm.
