With rime, moisture comes from freezing Atomization of water droplets, directly from liquid to solid, or by direct freezing. Hoarfrost, on the other hand, occurs on a clear, cold night when water vapor sublimates: an immediate transition from a gaseous state to a solid state.

Is it hoarfrost?

Hoarfrost is a feathery cream Formed due to specific climatic conditions. The word ‘hoar’ comes from Old English and refers to the old look of frost: the way ice crystals form that makes it look like white hair or a beard.
