Why the snow scrunches?

Why the snow scrunches? 20.02.2014
So, today I will explain “why sometimes snow scrunches under the feet and sometimes not?”

When frost, in snowflakes crystals (which consists of water, as you already know from the previous posts) form new interlayers from the freezing water, which play the role of bridges between the parts of snowflakes.

The lower the temperature, the more interlayers appear and the stronger is snowflake. When we walk on the snow, snowflakes are breaking and we hear that special sound.

But when the snow has fallen and the temperature is about 0 degree, we’ll hear no sound, because the new interlayers of water will not freeze.

I’m waiting for your next questions!
