Thunderstorm video quiz

What are the three basic ingredients required for a thunderstorm to form?

• Wind, rain, and lightning

• Moisture, unstable air, and lift

• Cold air, warm air, and clouds

• Ocean currents, evaporation, and updrafts

What atmospheric conditions lead to the formation of unstable air, a key ingredient for thunderstorms?

• Warm, moist air above cold, dry air

• Cold, dry air near the ground with warm, moist air above

• Warm, moist air near the ground with cold, dry air above

• Equal temperatures and moisture levels throughout the atmosphere

How does 'lift' contribute to the growth of a thunderstorm cloud?

• It causes cold, dry air to sink, suppressing cloud formation.

• It creates strong horizontal winds that spread the cloud.

• It makes warm, less dense air rise upward, causing the cloud to grow taller.

• It reduces the amount of moisture in the air, preventing heavy rain.

What causes a thunderstorm to begin weakening?

• When it runs out of downdrafts.

• When the updrafts are no longer able to fuel the storm with warm, moist air.

• When the cloud reaches its maximum height of 10 miles.

• When the rain and wind become too intense.
