 [How does Thunder and Lightning happen?


Introduction


Thunder is loud, can frighten pets and is dangerous near water.

Thunder and lightning is noisy, bright and can be dangerous.


But how is it caused?






  1. How does Thunder make noise?

Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder.




  1. How does lightning get colour?


Lightning color is caused by light emitted as the electrons drop back to their original energy. 


Seen from above, lightning storms also produce less

well known colors can be seen, different types of blue or red light above clouds. Known as jets and sprites.










  1. Why is lightning dangerous near water?


Lightning strikes are not  only dangerous but are deadly.


A direct strike is not the only way a lightning bolt can kill.


When lightning strikes land, it spreads through  the surrounding ground . We know that water is a good conductor of electricity. So if lightning hits water,  it will create a current of electricity. 






Conclusion




Lightning is dangerous near water and thunder can make loud noise
