During a storm, convection currents cause a separation of charges in storm clouds, and then lightening strikes the ground due to...

• the force of the convection currents

• the attraction between negative and positive charges between the cloud and the ground

• the negative and positive charges in the cloud repelling each other

• the high potential energy in the cloud flowing to the low potential energy in the ground
