Snowflakes are one of the many recognisable symbols of winter weather. Every snowflake is unique and there is one infinite variety of possible forms they deserve to form.

You are watching: How many points does a snowflake have?

What is a snowflake?

A snowflake starts life together a tiny droplet that supercooled water i m sorry freezes in the skies to create an ice crystal. The droplet becomes frozen either since temperatures are sufficiently cold (it would need to be −35 °C or lower) to frozen to various other droplets, or in clouds above -35 °C, they can form around a nucleus such as a dust or pollen particle.

Once the ice crystal has actually formed, if the problems are ideal it will begin to grow, together water molecule in the air room deposited top top the ice decision as it falls through the air, and also clump with each other to form a snowflake.

Why room snowflakes hexagonal?

All snowflakes contain six sides or points fan to the method in which castle form. The molecule in ice crystals join to one one more in a hexagonal structure, an plan which allows water molecule - each through one oxygen and two hydrogen atoms - to kind together in the most reliable way.

Snowflakes are unique

Part that the enduring very nice one of snowflakes is their complex appearance and also near boundless variation, often leading come the assertion the all snowflakes are unique. When this in part sense impossible to test, together a general rule it is totally true. The number of possibilities of alters in temperature and humidity as the snowflake drops to the floor is limitless. If girlfriend look very closely at a snowflake you will see countless individual features, all of which can have formed ever before so slightly in different way in direction or form owing to the slightest change in the atmosphere in which that formed.

What renders snowflakes white?

While snowflakes appear white together they fall through the sky, or as they accumulate on the ground as snowfall, they room in fact entirely clear. The ice is not transparent prefer a paper of glass is, however rather is translucent, an interpretation light passes through however not directly. The many sides that the ice cream crystals cause diffuse reflection of the entirety light spectrum which outcomes in snowflakes showing up to be white in colour.

Types the snowflake

Whilst the variation of snowflake forms is infinite, they deserve to be broadly categorised into groups which give an indication regarding what problems the snowflake formed in. Three of the broad varieties are:

endrite snowflake

Perhaps the many eye-catching kind of snowflake, the name way 'tree-like' recognising your branching structures . They form in very low temperature of -20 come -25 °C whereby the atmosphere contains numerous moisture to allow the snowflake to kind intricate patterns.



Thin plate

Plates are basically part-formed dendrites, the begin to type their complex patterns yet cannot achieve sufficient moisture to kind the branches so kind a less complex flat plate. These have tendency to type at warmer temperatures wherein there is less moisture in the air.

Sector plate

Similar come a thin plate, a ar plate snowflake again lacks moisture but forms a hexagonal structure regularly with a star-like form in the centre and the more visible attempts come branch.
