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.
Lightning can occur between opposite charges within the thunderstorm cloud (intra-cloud lightning) or between opposite charges in the cloud and on the ground (cloud-to-ground lightning).Lightning is one of the oldest observed natural phenomena on earth.ightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.
