Understanding Hailstones

The video discusses a giant hailstone that fell from the sky, measuring 20 cm across. It explains how hailstones form during thunderstorms when raindrops are lifted by strong winds and freeze into ice. These hailstones can grow larger as they circulate in the clouds before falling to Earth. The video highlights a record-breaking hailstone found in South Dakota in 2010, which remains the largest ever recorded. However, with the right conditions, a new record could be set in the future.

What natural phenomenon is responsible for the formation of hailstones?

• Earthquakes

• Thunderstorms

• Volcanic eruptions

• Tornadoes

How do hailstones increase in size while in the clouds?

• By colliding with other hailstones

• By melting and refreezing

• By collecting more raindrops

• By absorbing sunlight

Where did the record-breaking hailstone fall in 2010?

• California

• Texas

• Florida

• South Dakota

What is the significance of the hailstone that fell in South Dakota?

• It was the coldest hailstone ever measured

• It was the heaviest hailstone ever recorded

• It was the first hailstone to be photographed

• It was the widest hailstone ever found

What could lead to a new record-breaking hailstone in the future?

• A decrease in global temperatures

• A particularly strong thunderstorm

• An increase in rainfall

• A change in wind direction
