A thin layer of ice crystals that form on Earth's surface when temperatures fall below freezing is called A. Sleet B. Freezing rain C. Frost D. Hail

Frost forms under clear skies when moisture in the air condenses and freezes directly on surfaces—creating a beautiful crystalline layer that often looks like nature's delicate artwork. It typically appears on cold, calm nights when the air temperature drops below freezing, leading to picturesque but chilly mornings! If you're ever caught in a frosty situation, keep in mind that while it’s delightful to look at, frost can be harmful to crops and sensitive plants. Covering them with cloth or bringing potted plants indoors can help protect against the bite of late-season frosts. Just a little prep, and your greens will thank you!
