| It's
fun to play in the snow. |
Snow is a form of precipitation within the Earth's
atmosphere in the form of crystalline water ice,
consisting of a multitude of snowflakes that fall
from clouds. Since snow is composed of small ice
particles, it is a granular material. It has an
open and therefore soft structure, unless packed
by external pressure. Snowflakes come in a variety
of sizes and shapes. Types which fall in the form
of a ball due to melting and refreezing, rather
than a flake, are known as graupel, ice pellets
or snow grains. Snowfall amount and its related
liquid equivalent precipitation amount are determined
using a variety of different rain gauges...
