Final answer:
Rime ice is a frost that forms from supercooled water droplets in cold, damp clouds at temperatures near freezing, typically found on mountains at high altitudes.
Step-by-step explanation:
Rime ice is a type of frost that forms on surfaces exposed to cold, damp clouds or fog at temperatures of -2°C to 0°C. This ice forms when supercooled water droplets in the air come into contact with a surface that is below freezing. The supercooled droplets immediately freeze upon contact, resulting in a rough, white ice deposit. Rime ice typically forms in environments where the air is moist and cold, such as the higher altitudes where clouds are composed mostly of ice crystals and supercooled water droplets, particularly when there are strong winds. These conditions are often met in stratiform and cumulus clouds over mountains or other elevated terrain.
