Frost-covered branch. Hoar frost on a leaf and twigs of a tree. 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 British Columbia,Canada | |
