What makes thunder and lightning?
Zeus!! and Thor!!!
Lightning is an electric current- Storm clouds strengthen the electric forces created in the atmosphere. As drops of water rise through storm clouds, the electric charges in these drops are separated. http://museumvictoria.com.au/scidiscovery/lightning/whatmakes.aspA lightning strike can heat the air in a fraction of a second. When air is heated that quickly, it expands violently and then contracts, like an explosion that happens in the blink of an eye. It's that explosion of air that creates sound waves.
btw lightnig is from electrona and thunder is the sound lightning makes that why you see lightning before you hear anything
