Snowflakes seem like white stars falling from the sky.But they don’t always look white.Sometimes they appear to have other colors.Some are red,green,yellow,or black.There have been snowflakes of almost every shape.Think how it would seem to have these coming down all around you.Wouldn’t they look pretty?
Black snow came down in France one year.Another year gray snow fell in Japan.It was found that such snow was mixed with ashes.This made it seem dark.Red snow has come down in other countries.When this happened,it was mixed with red dust.That’s why it looked different.
Most snow looks white,but it is really the color of ice.It is ice that comes from snow clouds.Each snowflake begins with a small drop of water.More water forms around this drop.The way the water freezes gives the snowflake its shape.
No two snowflakes are ever just the same size or shape.All start out flat and have six sides.Some snowflakes are broken when they hit the ground.Others melt as they fall.When air is cold and dry,the falling snowflakes are small and hard.If the air is wet and warmer,the snowflakes are big and soft.
Would you be surprised to see snowflakes as big as your head falling from the sky?It happened once in our country.It could occur again.
