Lightning strike are caused by short, violent transfers of electric charges, either between one cloud and another, or between clouds and the earth. During a thunderstorm, the lower parts of clouds(the part nearest the earth) accumulate lots of negative electrical charges – whilst, on the ground, positives electrical charges accumulate. When there is a build-up of negatives charges in the sky, these charges move toward the positives charges on the earth and cause lightning.
