Answer 1

Answer:

Lightning

Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. ... Lightning causes thunder! Energy from a lightning channel heats the air briefly to around 50,000 degrees Fahrenheit, much hotter than the surface of the sun.

Precautions

✯

Avoid water during a thunderstorm. Lightning can travel through plumbing. Avoid electronic equipment of all types. Lightning can travel through electrical systems and radio and television reception systems.

✯Stay away from wire fences, clotheslines, metal pipes, rails and other metallic paths which could carry lightning to you from some distance away. Avoid standing in small isolated sheds or other small structures in open areas. In a forest, seek shelter in a low area under a thick growth of small trees.
