Lightning

1/    Grounding is when you remove the excess charge on an object by  the transfer of electrons between it and another object of substantial size, like the earth. 

2/ Induction charging is a method used to charge an object without actually touching the object to any other charged object

3/Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning -occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger.
