Frost-covered teasel (Dipsacus fullonum). Hoar frost on a seed head of a wild teasel plant. Hoar frost results when heat is lost through radiation into the open sky on cold clear nights,causing objects to become colder than the surrounding air. This temperature difference causes the water in the warmer air to condense on the colder objects and then freeze into small ice crystals. Photographed in Somerset,England,UK,in December | |
