How Hail Happens

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.

Which type of cloud forms hail?

• Altocumulus

• Cirrocumulus

• Nimbostratus

• Cumulonimbus

Check the option that is not true about hail:

• It falls from the clouds as balls of ice

• Is formed from violent air currents hurling ice pellets around in the clouds

• It has to be below freezing for hail to fall

• Is formed during thunderstorms

Which process describes the growth of hailstones in a cloud?

• Condensation

• Evaporation

• Accretion

• Sublimation

What is the primary factor that determines the size of a hailstone?

• Temperature

• Wind speed

• Updraft strength

• Cloud type

In which layer of the atmosphere does hail formation primarily occur?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What role do supercooled water droplets play in hail formation?

• They evaporate to cool the air

• They freeze onto ice nuclei

• They condense to form rain

• They cause lightning

How does the presence of a strong updraft affect hailstone development?

• It prevents hail formation

• It causes hailstones to melt

• It allows hailstones to grow larger

• It disperses hailstones
