Jean Baptiste Lamarck and others recognized that this nested, hierarchical pattern would be produce if organisms evolved from common ancestors. Systematics is the study of the diversity and relationship of organisms (how these organisms are named and classified is the discipline of taxonomy).
In addition to the visible flash that travels through the air, the current associated with the lightning discharge travels along the ground. Although some victims are struck directly by the main lightning stroke, many victims are struck as the current moves in and along the ground. â¢ If you can hear thunder, you are within 10 miles (16 kilometers) of a stormâand can be struck by lightning. Seek shelter and avoid situations in which you may be vulnerable.
The ability of a storm cloud's electric fields to transform air into a conductor makes charge transfer (in the form of a lightning bolt) from the cloud to the ground (or even to other clouds) possible.A lightning bolt begins with the development of a step leader.Excess electrons on the bottom of the cloud begin a journey through the conducting air to the ground at speeds up to 60 miles per second. These electrons follow zigzag paths towards the ground, branching at various locations.uildings, trees and even people can experience a buildup of static charge as electrons are repelled by the cloud's bottom. With the cloud polarized into opposites and with a positive charge induced upon Earth's surface, the stage is set for Act 2 in the drama of a lightning strike.
