Crystal structure morphology as a function of temperature and water saturation Temperature range Saturation range (g/m 3) Types of snow crystal below saturation Types of snow crystal above saturation 0 °C (32 °F) to −3.5 °C (26 °F) 0.0 to 0.5 Solid plates Thin plates Dendrites −3.5 °C (26 °F) to −10 °C (14 °F) 0.5 to 1.2
Snow accumulation on ground and in tree branches in Germany Snow blowing across a highway in Canada Spring snow on a mountain in France. Classifications of snow describe and categorize the attributes of snow-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time.
It also has a more extensive classification of deposited snow than those that pertain to airborne snow. The categories include both natural and man-made snow types, descriptions of snow crystals as they metamorphose and melt, the development of hoar frost in the snow pack and the formation of ice therein.
Snow sliders – The ability of a ski or other runner to slide over snow depends on both the properties of the snow and the ski to result in an optimum amount of lubrication from melting the snow by friction with the ski—too little and the ski interacts with solid snow crystals, too much and capillary attraction of meltwater retards the ski.

The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts , typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres.
The Inorganic Crystal Structure Database (ICSD) in its definition of "inorganic" carbon compounds, states that such compounds may contain either C-H or C-C bonds, but not both. [7] The book series Inorganic Syntheses does not define inorganic compounds. The majority of its content deals with metal complexes of organic ligands. [8]
Fluid inclusions in crystals from the mantle have contents that most often are liquid carbon dioxide, but which also include carbon oxysulfide, methane and carbon monoxide [6] Material is added by subduction from the crust. This includes the major carbon containing sediments such as limestone, or coal.
