The first step has been numbered for you.13. The electric field surrounding the excess electrons in the bottom of the storm cloudrepels electrons in the ground.Charges move quickly from the cloud to the ground, causing a flash of lightning.During a storm, air currents in storm clouds cause electrons to be transferred fromthe top of the cloud to the bottom.The ground beneath the storm cloud becomes positively charged.Directions: Explain how a lightning flash can occur within a storm cloud.14.1Chapter7Electricity and Magnetism 23
