How is it formed? Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges.
Why is lightning always attracted to trees? Actually, all trees attract lightning. They are tall and usually filled with moisture, thus providing a good electrical conducting path for lightning. Every day, thousands of trees are hit by lightning throughout the world. Oak trees are the most vulnerable because they are taller than the others.
Can you harness the electricity from lightning? People have considered harnessing lightning for electrical power, but no serious attempts are currently under way, nor are any planned. Also, lightning would have to be collected over a huge area, making the system impractically expensive.
What are your chances of being struck by lightning?
The chance of an average person living in the US being struck by lightning in a given year is estimated at 1 in 500,000, while the chance of being struck by lightning in a lifetime is 1 in 6250 (estimated lifespan of 80 years).
How to avoid getting struck by lightning? 1.Avoid being out in any open areas. 2.Stay away from any metal. 3.If you are in a pool, get out of it, water is a conductor. 4.Don't stand under tall objects. 5.Ditch your umbrella. 6.And find a car and get in it.
What are the effects of getting struck by lightning? Immediate effects:The most critical injuries are to the circulatory system, the lungs, and the central nervous system but injuries also occur to other body systems. The long term effects are: ruptured eardrums, cataracts, memory deficit, sleep disturbance, chronic pain and dizziness.
THANKS FOR WATCHING!
HOPE YOU ENJOYED IT!
