4. Moisture evaporates in the air. Snow falls into warm air and melts into rain. An ice storm is a type of winter storm caused by freezing rain.

5. Winter Storms  Sleet is just rain drops that freeze into ice pellets before reaching the ground.  Ice storms form when a layer of warm air is between two layers of cold air.  Snowflakes are made of ice crystals.

6. Winter Storms  Freezing rain is just rain that falls onto a surface with a temperature below freezing.  An avalanche is a moving mass of snow that may contain ice, soil, rocks, and uprooted trees.  Frozen precipitation melts while falling into the warm air layer, and then proceeds to refreeze in the cold layer above the ground.

7. Winter Storms  Snow forms when water vapor in the atmosphere freezes into ice crystals.  Light and fluffy snow is often called powder.  Snowstorms with high winds are often called blizzards.  Heavy snowfalls are often called snowstorms.
