Understanding Hail Formation

The video explains that hail is ice that falls from thunderstorms and other tall clouds. It forms when water droplets freeze in below-freezing air, often lifted by updrafts in thunderstorms. Hailstones can grow larger by accumulating more ice layers, especially in strong upward winds. Large hail can be damaging, with the largest recorded hailstone weighing nearly two pounds. The video is presented by meteorologist Alan Seals.

What is hail primarily composed of?

• Snowflakes

• Dust particles

• Ice pieces

• Water droplets

How does hail form in a thunderstorm?

• By melting snowflakes

• By freezing water droplets in below-freezing air

• By mixing with rain

• By condensation of water vapor

What role do updrafts play in hail formation?

• They melt the hailstones

• They cause hailstones to fall

• They lift water droplets into freezing air

• They prevent hail from forming

What can cause hailstones to grow larger in a thunderstorm?

• Weak winds

• Strong upward winds

• High temperatures

• Low humidity

What was the size of the largest recorded hailstone?

• The size of a tennis ball

• The size of a grapefruit

• The size of a baseball

• The size of a golf ball
