Snow. Snow forms when ice crystals reach the earth’s surface without passing through a liquid phase.
Snow is a type of precipitation that occurs when water vapor in the atmosphere freezes into ice crystals. The shape and size of the snowflakes depend on the temperature and humidity of the air.
Snow can fall as light flakes, heavy flakes, or pellets. Snow can accumulate on the ground and form snowpacks, drifts, or avalanches. Snow can also melt and refreeze into ice or slush.
Some examples of snow-related topics are:
Snowflakes: the individual ice crystals that form snow. Snowflakes have a hexagonal symmetry and a variety of patterns. No two snowflakes are exactly alike.
Snowstorms: weather events that produce a large amount of snow in a short period of time. Snowstorms can cause low visibility, strong winds, and cold temperatures. Snowstorms can also create hazards such as power outages, traffic accidents, and frostbite. Some types of snowstorms are blizzards, nor'easters, and lake-effect snow.
