Which type of ice consists of both clear and rime ice formed at the same time?

The correct answer is mixed ice, which refers to the phenomenon where both clear ice and rime ice form simultaneously. Clear ice forms when supercooled water droplets freeze upon contact with surfaces, creating a smooth and transparent layer of ice. On the other hand, rime ice develops when water vapor freezes on cold surfaces, leading to a more opaque, white appearance.

In instances where conditions favor the concurrent formation of these two types of ice—such as during freezing rain or specific atmospheric conditions—mixed ice will emerge. This form combines the characteristics of both ice types, showcasing areas of smooth, transparent ice alongside areas that are more textured and white due to rime ice. Understanding the formation process of mixed ice can help in predicting potential hazards in winter weather, such as icy roads or power lines.
