Ice crystals

Ice crystals are solid ice exhibiting atomic ordering on various length scales and include hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust.

Liquid water is densest, essentially 1.00 g/cm 3, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the freezing point is reached.

This meteorological phenomenon is also referred to simply as ice crystals and is reported in the METAR code as IC.

Ice clouds are composed of ice crystals, the most notable being cirrus clouds and ice fog.

Ice fog is a type of fog consisting of fine ice crystals suspended in the air.

Ice clouds are composed of ice crystals, the most notable being cirrus clouds and ice fog.

Cirrus clouds range in thickness from 100 m to 8000 m, with an average thickness of 1500 m. There are, on average, 30 ice crystals per liter (96 ice crystals per gallon), but this ranges from one ice crystal per 10,000 liters (3.7 ice crystals per 10,000 gallons) to 10,000 ice crystals per liter (37,000 ice crystals per gallon), a difference of eight orders of magnitude.

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.

Ice crystals are solid ice exhibiting atomic ordering on various length scales and include hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust. Common ice crystals are symmetrical and have a hexagonal pattern.

The hugely symmetric shapes are due to depositional growth, namely, direct deposition of water vapour onto the ice crystal.

Possible shapes for ice crystals are columns, needles, plates and dendrites.

The slight whitening of a clear blue sky caused by ice crystals high in the troposphere can be a sign that a weather front (and rain) is approaching, as moist air is carried to high levels and freezes to ice crystals.

Square ice crystals form at room temperature when squeezed between two layers of graphene.

The research derived from the earlier discovery that water vapor and liquid water could pass through laminated sheets of graphene oxide, unlike smaller molecules such as helium.

The effect is thought to be driven by the van der Waals force, which may involve more than 10,000 atmospheres of pressure.
