Hail Formation and Updrafts Quiz

How does hail form in clouds?

• By water droplets evaporating

• By water droplets freezing and colliding

• By water droplets melting

• By water droplets condensing

Which size of hailstone requires the highest updraft speed according to the table?

Why do hailstones grow larger in clouds with strong updrafts?

• They absorb more sunlight

• They collide with more water droplets

• They freeze faster

• They fall to the ground quickly
