Explanation:
The mechanism of a lightning stroke is typically explained as follows. As the negative charges build up in the cloud base, positive charges are induced on the ground. ... As this stepped leader (or downward leader) nears the ground, the upward leader (or return stroke) is initiated that meets the downward leader.

Answer:
A typical cloud-to-ground lightning bolt begins when a step-like series of negative charges, called a stepped leader, races downward from the bottom of a storm cloud toward the Earth along a channel at about 200,000 mph (300,000 kph). Each of these segments is about 150 feet (46 meters) long.
