Introduction of Snow in English

Snow is a kind of precipitation in the earth's atmosphere, which exists in the form of crystal water ice and consists of a large number of snowflakes falling from the clouds. Because snow is composed of small ice particles, it is a granular substance. It has an open and therefore soft structure, unless the packaging is under external pressure. Snowflakes come in all sizes and shapes. The type that is spherical rather than flaky due to melting and refreezing is called graupel, and ice particles and snow particles are examples of graupel. Different rain gauges are used to determine the snowfall and its related liquid equivalent precipitation.
