Virtually all ice in the biosphere is ice I h (pronounced: ice one h, also known as ice-phase-one). Ice I h exhibits many peculiar properties that are relevant to the existence of life and regulation of global climate. [140] For instance, its density is lower than that of liquid water.

Cubic ice (Ice I c) is a metastable b ice crystal that can be formed (a) by condensation of water vapor at ambient pressure but at less than -80 °C, see Phase Diagram), (b) below about -38 °C in tiny droplets (≈ 6 μm diameter) , and (c) by reducing the pressure on high-pressure ices at 77 K. Cubic ice is usually found as transitional ...
