A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions.... form of ice
Ice
Ice is a solid phases of matter, usually crystalline solid, of a non-metallic substance that is liquid or gas at room temperature, such as ammonia ice or methane ice.... including hexagonal

In geometry, a hexagon is a polygon with six edges and six Vertex . A regular hexagon has Schl?fli symbol .... columns, hexagonal plates, dendritic crystals
Dendrite (crystal)
A crystal dendrite is a crystal that develops with a typical multi-branching tree-like form. Dendritic crystal growth is very common and illustrated by snowflake formation and frost patterns on a window.... , and diamond dust
Diamond dust
Diamond dust is a ground-level cloud composed of tiny ice crystals. This List of meteorological phenomena is also referred to simply as ice crystals and is reported in the METAR code as IC.... .
In physics, temperature is a physical property of a Physical system that underlies the common notions of hot and cold; something that feels hotter generally has the greater temperature.... and water vapor
Water vapor
Water vapor or water vapour , also aqueous vapor, is the gas phase of water . Water vapor is one Phase of the water cycle within the hydrosphere.... humidity
Humidity
Humidity is the amount of water vapor in the air. In daily language the term "humidity" is normally taken to mean relative humidity. Relative humidity is defined as the ratio of the partial pressure of water vapor in a Air parcel of air to the saturated vapor pressure of water vapor at a prescribed temperature.... determine crystalline forms. Ice crystals are responsible for various atmospheric
Atmosphere
An atmosphere is a layer of gases that may surround a material body of sufficient mass, by the gravity of the body, and are retained for a longer duration if gravity is high and the atmosphere's temperature is low.... optics displays. The principal axis
Principal axis theorem
In the mathematics fields of geometry and linear algebra, a principal axis is a certain line in a Euclidean space associated to an ellipsoid or hyperboloid, generalizing the ellipse.... (c axis) of a single crystal of ice is perpendicular

Ice clouds are composed of ice crystals. The most notable one is the cirrus cloud
Cirrus cloud
Cirrus clouds are characterized by thin, wisplike strands, often accompanied by tufts, leading to their common name of mare's tail. Sometimes these clouds are so extensive that they are virtually indistinguishable from one another, forming a sheet of cirrus called Cirrostratus cloud.... and ice fog.
Snow is a type of precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds. The process of this precipitation is called snowfall....
