How is Rime Ice best described?

Brittle and frost-like
Soft and wet
Smooth and flowing
Dark and heavy

The correct answer is: Brittle and frost-like

Rime ice is best described as brittle and frost-like due to its formation process. This type of ice occurs when supercooled water droplets collide with a surface at or below freezing temperatures. Upon impact, these droplets freeze instantly, creating a rough, opaque, white layer of ice. This ice accumulation often gives it a crystalline appearance and an appearance similar to frost, which is where the characterization as "frost-like" comes from. Its brittle nature indicates that it can easily break off or shatter when subjected to pressure or changes in temperature, contrasting with other types of ice, which may exhibit different properties. Understanding the characteristics of rime ice is important for pilots and dispatchers, as it can significantly impact flight operations and safety.
