Understanding Tornadoes

Tornadoes, also known as twisters, are violent storms with winds up to 300 mph, primarily occurring in the US. They form when warm, moist air from the Gulf of Mexico meets cold air from Canada, creating supercells. Tornadoes cause significant damage and loss of life, but scientists and storm chasers are working to improve prediction and safety measures.

What is the maximum wind speed that tornadoes can reach?

• 150 miles per hour

• 200 miles per hour

• 400 miles per hour

• 300 miles per hour

Which area in the US is most frequently hit by tornadoes?

• The West Coast

• The Great Plains

• The East Coast

• The Rocky Mountains

What is the primary cause of supercells that can lead to tornadoes?

• Volcanic eruptions

• Ocean currents

• Earthquakes

• Interaction of warm and cold air masses

What role does warm moist air play in tornado formation?

• It disperses the storm

• It prevents tornadoes

• It helps in forming a rotating column of air

• It cools down the storm

What indicates that a tornado is imminent?

• Heavy snowfall

• Clear skies

• A low-hanging revolving cloud forms

• A sudden drop in temperature

How long do tornadoes typically last?

• Several days

• A few hours

• 20 seconds to an hour

• A week

What is a recommended safety measure when a tornado is spotted?

• Go outside to watch it

• Stay near windows

• Go to a basement

• Climb to the roof

What do storm chasers aim to achieve by studying tornadoes?

• To create more powerful storms

• To predict when and where tornadoes will strike

• To stop tornadoes from forming

• To increase the number of tornadoes

What tools do scientists use to measure tornadoes?

• Specialized instruments

• Thermometers

• Barometers

• Seismographs

What is the ultimate goal of improving tornado forecasting?

• To increase storm frequency

• To save lives and aid in rebuilding

• To make storms more predictable for entertainment

• To eliminate tornadoes
