Why is snow white?
● One of the reasons that so many people love snow is that it coats everything in a
clean, “pure” white blanket.
● Snow forms when water vapor in the atmosphere freezes. As the vapor
freezes clear transparent crystals are formed. The Currents that are in the air
make these crystals go up and down in the atmosphere and they begin to gather
around tiny particles that are in the clouds. When a group of ice crystals is big
enough, it floats down to Earth as a snowflake.
● The crystals that make up a snowflake always form six-pointed stars. No two
snowflakes have ever been found to be exactly alike.
● Each snowflake is made up of individual ice crystals arranged together. When a
light photon enters a layer of snow, it goes through an ice crystal on the top,
which changes its direction slightly and sends it on to a new ice crystal, which
does the same thing.
