Why do thunderstorms produce hail?
Show answer & explanation
Answer: Ice is thrown up and down in clouds
Ice is thrown up and down in clouds ✓ — Correct! Hail forms in powerful thunderstorms with strong updrafts. Ice particles get lifted above the freezing level, collect supercooled water droplets, freeze, then fall. But updrafts throw them up again! This cycle repeats, building concentric ice layers like an onion. When hailstones grow too heavy for updrafts to lift (some reach baseball size!), they finally fall to the ground.
Lightning freezes water droplets — Wrong. Lightning doesn't freeze water - it's an electrical discharge. Hail forms when strong updrafts repeatedly cycle ice through freezing zones, building layers of ice.
Cold air meets warm storms — Wrong. While thunderstorms have temperature contrasts, hail specifically forms when strong updrafts repeatedly lift ice particles through freezing levels, allowing layers to accumulate.
