Yes, it’s true! Just
like human fingerprints are each different, every snowflake is different,
although each snowflake is made up of thousands of tiny, identically shaped
hexagonal (six-sided) crystals gathered together. There are many reasons
that no two snowflakes are alike. Snowflakes form by sticking to each
other while falling and blowing through the wind.
Factors that influence the size and shape of a
snowflake are:
·
Air
currents (which direction the air is moving)
·
Humidity
levels (the amount of water vapor in the air)
·
How long
it takes the crystal to fall
·
Wind
speed
·
Amount of
dust, salt or other solid particles in the air
·
Pressure
from the weight of other snow crystals
·
Combining
shapes with other snow crystals
·
Changes
to any of these factors
