What is the main difference between hail and ice pellets?

Hail consists of balls of ice, while ice pellets are a form of solid precipitation.

Hail falls during cold weather, whereas ice pellets grow during low surface temperatures.

Hailstones are irregular lumps of ice, while ice pellets are smooth.

Hail growth is inhibited during low surface temperatures, but ice pellets generally fall in cold weather. (correct)

Which type of humidity is based on the actual amount of water vapor present in the air?

Absolute Humidity (correct)

Dew Point Humidity

Vapor Pressure Humidity

Relative Humidity

What does humidity indicate the likelihood for?

Blizzards

Rainbows

Thunderstorms

Precipitation, dew, or fog (correct)
