They’re ice crystals that kind on soil, automobiles, tree leaves, and different flooring when moisture within the air instantly solidifies.
HOW RIRES IS MADE
If the air temperature drops under 0°C, it is not adequate for the formation of frost. As well as, the air should be sufficiently humid to start with; nonetheless, such an air mass turns into saturated because it cools, and extra cooling after this level causes condensation.
When there is not sufficient moisture, frost doesn’t kind, however plant tissues can freeze and a phenomenon referred to as black frost happens.
