Hoarfrost is a type of frost that forms long ice needles on objects when the air is moist and cold. Learn how hoarfrost differs from rime ice and where to find it in the winter.
21 de feb. de 2019 · Hoar frost is a type of feathery frost that forms when water vapour freezes on surfaces below 0°C. Learn how hoar frost differs from ground frost, how it looks like white hair or a beard, and how it affects trees.
Hoar frost, also hoarfrost, radiation frost, or pruina, refers to white ice crystals deposited on the ground or loosely attached to exposed objects, such as wires or leaves. They form on cold, clear nights when conditions are such that heat radiates into outer space faster than it can be replaced from nearby warm objects or brought ...
Hoarfrost is a deposit of ice crystals on objects exposed to the free air, formed by direct condensation of water vapour to ice at temperatures below freezing. Learn about the conditions, processes, and forms of hoarfrost, as well as its effects on plants and crops, from Britannica.
