Thunder


We know that lightning coming down from the sky is really hot, and that it is excited electrons zapping down as plasma.

The change in temperature and pressure as the lightning is zapping the ground causes the air around it to get pushed out really really fast.
That pushing of all the air around it creates what is called a shockwave that makes a huge sound which is the thunder we hear.
