Lightning & Rubber Shoes

It is believed that lightning is a form of static discharge. Static discharge means that some particles (usually electrons) leave its object and move to different place. So what does the lightning cause? It is has to do the static discharge in the storms. When there is a storm in the sky, it will make the clouds and particles in the sky dash to one another. When they push one another violently, their electrons and protons separate or the electrons move to somewhere else. After a while, all electrons and protons are separated. The positive charged will stay on the top of the clouds and the negative charged will move to the bottom of the clouds. When the negative charged are at the bottom of the clouds, it will induce the positive charged from the surface of the ground. Again, the negative charged from the bottom of the clouds move to the surface of the ground where the positive charged exist. When the negative charged move, there is some energy from the release of the discharging process. It is the releasing energy that causes the lightning.
During a storm, it is better to wear rubber shoes because rubber is one of the insulators. Insulator can make the charge difficult to move or pass. So when we wear rubber shoes in a storm, the charge cannot pass on our bodies and we can avoid the lightning or thunder on our heads.
