43. Tornados: Frightening Storms

According to the essay, why is a tornado's funnel cloud visible?
1. Because it is made of lightning and rain.
2. Because it collects dust, water droplets, and debris.
3. Because the wind inside it is colored dark grey.
4. Because it reflects sunlight from the thunderstorm.
What two conditions are necessary for a tornado to form?
1. A supercell storm and a strong downdraft.
2. Warm, wet air near the ground and cool, dry air above it.
3. High pressure and low pressure colliding.
4. Fast winds and a horizontal tube of air.
How do scientists determine the strength of a tornado on the Enhanced Fujita (EF) scale?
1. By measuring the wind speed directly with special radar.
2. By calculating the tornado's size and duration.
3. By analyzing the damage it leaves behind.
4. By tracking its path and speed across the ground.
What should you do immediately when a Tornado Warning is issued?
1. Go outside to see if you can spot the tornado.
2. Open your windows to equalize the air pressure.
3. Move to a safe shelter like a basement or interior room.
4. Get in your car and try to drive away from the storm's path.
Based on the essay, what is the correct sequence of events in the formation of a tornado?
1. Updraft tilts a spinning tube -> Air masses meet, creating instability -> Horizontal tube of air forms -> Column touches the ground.
2. Air masses meet, creating instability -> Horizontal tube of air forms -> Updraft tilts the spinning tube -> Column touches the ground.
3. Column touches the ground -> Horizontal tube of air forms -> Updraft tilts the spinning tube -> Air masses meet.
4. Horizontal tube of air forms -> Column touches the ground -> Air masses meet -> Updraft tilts the spinning tube.
