The Wonderful World Of Snowflakes
Transcript of The Wonderful World Of Snowflakes
how do snowflakes form
Snowflakes usually come in the shape of a star
Ice crystals create snowflakes and snowflakes create snow
When rain falls on snow, the snow either melts or turns into slush on the road.
What Are Snowflakes
Snowflakes are formed in the clouds, this happens when water droplets freeze and become ice particles. Water vapour in the cloud assembles on the ice particle, causes it to stretch into a basic hexagonal prism and then to shoot branches to create a more difficult and complex shape, once this has happened snowflakes then change even more to make them unique. The temperature and dampness of the cloud constantly changes, which affects the shape of each snowflake.
What are snowflakes made out of
what are the sizes of snowflakes
what color are snowflakes
You may think snowflakes are white but that is not true. Snowflakes are crystal clear, but the sun reflects the color of the snow and makes the snowflakes look white.
In what weather do snowflakes form
The temperature in the highest clouds is around -30°F and they are made up exclusively of ice crystal columns. The other three shapes are formed in a narrow temperature range. When the temperature in the clouds is 3° to 10°F the star shaped crystals form. From 10°-18°F the plates form, and from 18°-23°F columns form. From 23°-27°F needles form and from 27°-32°F the plates reappear. As the snow crystals grow they become heavier and fall towards Earth. If they spin like tops as they fall then they may be perfectly symmetrical when they hit the Earth. But if they fall in a sideways fashion then they end up lopsided. Falling snow crystals clump together forming snowflakes.

Snowflakes are made out of pure snow which is made up of snowflakes, and snowflakes are made up of from 2 to 200 separate snow crystals.
Snowflakes sizes can be from 0.1centimeters to 1 inch. The largest snowflake that was ever seen was 15 inches wide and 8 inches thick
A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake.
