Did you know volcanoes can produce lightning? Scientists aren't completely sure how it works, but they have an idea it may relate to the kinetic energy of particles. One hypothesis claims that projected magma or volcanic ash itself is electrically charged, and by its motion creates lightning. Electrical energy in magma or ash is a type of kinetic energy because the charges are moving. Know we know what killed the dinos
