Hail

Hail can fall up to _____ mph.

• 9 miles per hour

• 25 miles per hour

• 100 miles per hour

• 75 miles per hour

How do hailstones grow?

• ice crystals collide

• Liquid water collides with ice & freezes to the surface

• water vapor freezes in a cloud

• Deposition

What makes a hailstone fall from the sky?

• The storm is over

• Gravity got stronger

• The updraft became weaker than the force of gravity pulling on the hail stone

Where do hailstorms form specifically?

• wind

• hurricanes

• Thunderstorm updrafts

• currents

What is the relationship between updraft speed and hailstone size according to the table?

• There is no clear relationship; hailstone size is random regardless of updraft speed.

• Smaller hailstones are associated with faster updraft speeds.

• Larger hailstones are associated with slower updraft speeds.

• Larger hailstones are associated with faster updraft speeds.

During a science class, Charlotte asked, 'Which of these best shows the correct sequence that forms hail during a typical storm?'

• rain falls --> freezes --> melts

• snow falls --> melts --> freezes again

• snow falls --> melts --> stays melted

• rain falls --> freezes --> gets blown back up --> melts --> falls again --> refreezes --> repeats multiple times

Which answer correctly explains the difference between sleet and hail?

• Sleet is usually part of a thunderstorm, and hail comes from layers of rain clouds.

• Sleet is smaller than hail and usually falls in the winter, while hail usually falls in the summer. 

• Sleet and hail are the same except that sleet usually falls in summer and hail usually falls in winter.

• Sleet is snow that forms as it falls through cold air, and hail is rain that freezes when it hits the ground.
