A Jagged Look at Lightning 2 (Answers)
Well, some of you have waited a week to find out how well you fared on the Lightning Quiz. Drum roll, please. Here are the answers:

1. True. According to http://www.ucar.edu/, Florida and the Rocky Mountain region do receive the most lightning.
2. False. I always thought this was true, but most the sites on my source list debunk it. They say that although rubber doesn’t conduct electricity, you do conduct it -- and rubber doesn’t lend you much, if any, protection.
3. False. Because lightning can run along the ground, your chances of being shocked are greater if you’re lying on the ground.
4. False. Lightning likes tall objects. Trees are a favorite. If you have to hide under a tree, look for one that’s shorter than others around it. .
5. True. Lightning is approximately 54,000 degrees Fahrenheit.
6. True. Each flash of lightning may be three to four lightning strikes. This is why lightning appears to flicker.
7. True. When lightning shoots toward the ground, it opens up a channel in the air. Once the light leaves the channel, the air around it collapses, creating the sound of thunder.
8. True. When counting between the sighting of lightning and hearing of thunder, every five seconds equals one mile.
9. False. Apparently lightning can strike 10 miles away from the storm. Because light waves travel faster than sound, lightning can strike long before thunder is heard.
10. False. Lightning actually can -- and often does -- strike in the same place. In fact it can hit favored places multiple times in a storm.
11. True. Accordingtohttp://lighteningstorms.suite101.com, the Empire State Building is struck an average of 100 times per year. Thank goodness for its elaborate system of safeguards.
12. False. As long as you don’t touch the metal of your car, it should keep you almost as safe as being indoors, but that is due to the structure around you, not the rubber tires.
13. True. According to several of my sources, the average person actually does have a 1 in 600, 000 chance of being hit by lightning.
Disclaimer: Although I’ve tried to verify these facts by using multiple sources and cross-referencing them, I’m not an actual researcher and – as you might guess – I haven’t tested these facts in person.
