Snow, a miraculous product of nature, has inspired people's imagination since ancient times. But in addition to its beauty and poetry, snow hides a lot of interesting trivia.
First of all, you know what?Snow is not always white. Actually, the color of snow depends on its crystalline form and the shape of the ice crystals. For example, if ice crystals contain bubbles during formation, white snow will form. But if the structure inside the ice crystals is aligned neatly, colored snow such as pink, green, etc., will be formed.
Secondly, snow is less dense than water. This means that if an object is covered in snow, its weight will increase but its volume will decrease. That's why the snowman gets taller and heavier.
Also, you wouldn't expect it, snow can also be different in hardness. Depending on the temperature and humidity, the hardness of snow can be graded from soft to hard. The hardest snow is called "dry snow", and it forms at low temperatures and contains little to no moisture. The softest form of snow is called "wet snow", which forms with higher humidity and contains more moisture.
Another interesting piece of trivia is that snow is actually a very dirty thing. Due to the dust and pollutants in the air, snow adsorbs these substances as it falls. As a result, even the purest snow contains some tiny particles and pollutants.
Finally, you might be surprised to know that in some places, snow doesn't always fall from the sky. In some places, snow is actually formed by groundwater or river freezing. This type of snow is known as "ice crystal snow", and it is often more pure and beautiful than snowflakes that fall from the sky.
In conclusion, there are many more trivia facts about snow that not only reveal the mystery and diversity of snow, but also give us a better understanding of the wonders of this natural phenomenon.
