Updraft vs Gravity

What is the main role of an updraft in hail formation?

• It pushes hailstones toward the ground.

• It pulls hailstones into the lower part of the storm.

• It lifts hailstones into the higher, colder parts of the storm where they can grow.

• It makes hailstones fall apart.

What causes a hailstone to fall to the ground?

• The temperature gets too hot.

• Gravity pulls it down when it becomes too heavy for the updraft to support.

• The hailstone shrinks until it falls.

• The wind blows it out of the cloud.

Why do larger hailstones take longer to fall than smaller ones?

• They are less effected by gravity.

• They float on the air more easily.

• Strong updrafts keep them in the cloud longer, allowing them to grow larger.

• The storm gets weaker as they fall.

How do hailstones grow larger inside a storm?

• By falling through warmer air.

• By collecting layers of ice each time the updraft lifts them.

• By melting & refreezing repeatedly.

• By merging with other hailstones.

Which of the following would most likely cause smaller hailstones?

• A very strong updraft.

• A long-lasting thunderstorm.

• A weak updraft that cannot lift hailstones very high.

• Colder temperatures in the storm.
