What is a Tornado?

Tornadoes are extreme weather events formed by updrafts and wind shear. The Fujita scale classifies their strength from F0 to F5. Despite understanding their basic formation, tornadoes remain unpredictable due to unknowns in how rotation intensifies. They can travel long distances, causing varying degrees of destruction.

What are the two main factors that contribute to the formation of a tornado?

• Updraft and wind shear

• Temperature and humidity

• Rainfall and lightning

• Pressure and altitude

What does the Fujita scale measure?

• The speed of tornadoes

• The strength of tornadoes

• The duration of tornadoes

• The frequency of tornadoes

What is the typical diameter of a tornado?

• Less than 250 meters

• 2 kilometers

• 500 meters

• 1 kilometer

What is one of the biggest challenges in understanding tornadoes?

• Determining their color

• Calculating their temperature

• Measuring their speed

• Predicting their exact path

Before a tornado forms, what is observed in the thunderstorm?

• Areas of rotation

• Heavy rainfall

• Lightning strikes

• High temperatures
