Weather-Hail Storms

What is the purpose of observing hailstone videos according to the Unit Overview/Summary?

• To learn about the equipment meteorologists use

• To observe what hailstones and hail storms look like and discover when they occur

• To analyze weather balloon data

• To discover the temperature decrease with altitude

According to the summary, which of the following is NOT a characteristic of hailstones?

• Hailstones can be as small as a grape

• Hailstones can be bumpy and lumpy

• Hailstones can be soft and squishy

• Hailstones can have rings (layers) inside

What was discovered about hail storms from the videos?

• Hail storms occur during winter months

• Hail storms are long-lasting

• Hail storms occur during months that we would not expect ice to form

• Hail storms occur only in tropical regions

What is a key finding from the weather balloon study mentioned in the Unit Overview/Summary?

• As altitude increases, hailstone size increases

• Weather balloons collect data from the surface up to 15,000 feet

• As altitude increases, temperature increases

• As altitude increases, temperature decreases

What do updrafts do in the formation of hail?

• Push raindrops down

• Push ice pellets up

• Push raindrops up

• Push ice pellets down

What happens to raindrops when they are pushed up by updrafts during the hail formation process?

• They evaporate

• They freeze

• They fall to the ground

• They break into smaller droplets

What is the role of downdrafts in the formation of hail?

• They push raindrops up

• They push ice pellets up

• They push ice pellets down

• They cause raindrops to evaporate

During the hail formation process, what happens to the ice pellets when they are pushed down by downdrafts?

• They melt

• They evaporate

• They get coated with water

• They break into smaller pieces

What continues to happen in "The Cycle" of hail formation until the wind is not strong enough?

• Ice pellets melt and evaporate

• Raindrops get coated with ice

• Layers or clumps form

• Hailstones are carried up and down
