Black ice is hard to see most of the time, but with the right lighting, drivers can look out for a smooth and glossy surface on the road to detect it. "If the majority of the road you're driving ...
Black ice on a road in Germany. Black ice, sometimes called clear ice, is a coating of glaze ice on a surface, for example on streets or on lakes. The ice itself is not black, but visually transparent, allowing the often black road below to be seen through it and light to be transmitted. The typically low levels of noticeable ice pellets, snow ...

Black ice is different from a white or grey layer of ice that can form when roadways have been plowed or driven on, packing the snow or hail so that it freezes into a slippery layer. Often ...
Radioglaciology is the study of glaciers, ice sheets, ice caps and icy moons using ice penetrating radar. It employs a geophysical method similar to ground-penetrating radar and typically operates at frequencies in the MF, HF, VHF and UHF portions of the radio spectrum.
Ice from a theorized superionic water may possess two crystalline structures. At pressures in excess of 50 GPa (7,300,000 psi) such superionic ice would take on a body-centered cubic structure. However, at pressures in excess of 100 GPa (15,000,000 psi) the structure may shift to a more stable face-centered cubic lattice.
Black ice is a scary sounding term, and for good reason: It leads to car accidents, injuries, and a fear of walking outside in the winter. But are you responsible to clear this invisible menace if ...
A rapid accretion and a slow dissipation of latent heat of fusion favor the formation of a transparent ice coating, without air or other impurities. A similar phenomenon occurs when freezing rain or drizzle hits a surface and is called glaze. Clear ice, when formed on the ground, is often called black ice, and can be extremely hazardous.
