here are some information on lighting !!
WHAT IS LIGHTNING ?
lightning is electricity.It forms in the strong up-and-down air currents inside tall dark cumulonimbus clouds as water droplets, hail, and ice crystals collide with one another The positive and negative electrical charges in the cloud separate from one another, the negative charges dropping to the lower part of the cloud and the positive charges staying ins the middle and upper parts.*Positive electrical charges also build upon the ground below. difference in the charges becomes large enough(force is strong to overcome the air resistance), a flow of electricity moves from the cloud down to the ground or from one part of the cloud to another, or from one cloud to another cloudour eyes fool us into thinking that the lightning bolt shoots down from the cloud, when *in fact the lightning travels up from the ground.
HOW THUNDER CLAP IS FORM ?
Lightning bolts are extremely hot which is even hotter than the surface of the sun with a temperature of 30,000 to 50,000 degrees F the heat of the lightning bolt cause the surrounding air to have a sudden expansion as a result, a LOUD claping sound sound is heard.
