Description
A snowflake is a single ice crystal that has achieved a sufficient size, and may have amalgamated with others, then falls through the Earth's atmosphere as snow.[1][2][3] Each flake nucleates around a dust particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants. The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of light by the small crystal facets of the snowflakes.
A Christmas decoration is any of several types of ornamentation used at Christmastime and the greater holiday season. The traditional colors of Christmas are pine green (evergreen), snow white, and heart red. Blue and white are often used to represent winter, or sometimes Hanukkah, which occurs around the same time. Gold and silver are also very common, as are other metallic colours. Typical images on Christmas decorations include Baby Jesus, Father Christmas, Santa Claus, and the star of Bethlehem. Typical winter icons include snowflakes, snowmen, icicles, and even penguins and polar bears.[citation needed]
In many countries, such as Sweden, people start to set up their Advent and Christmas decorations on the first day of Advent.[1][2] Liturgically, this is done in some parishes through a Hanging of the Greens ceremony.[3] In the Western Christian world, the two traditional days when Christmas decorations are removed are Twelfth Night and if they are not taken down on that day, Candlemas, the latter of which ends the Christmas-Epiphany season in some denominations.[4] Leaving the decorations up beyond Candlemas is historically considered to be inauspicious.
