Bolt Of Lightning example essay topic
The bolts have the capacity to injure many things, including appliances, people, forest, etc. However, although these bolts can have dangerous affects, there are prevention techniques for lightening. These procedures can protect you, loved ones, and property. With lightning come many myths. These myths can endanger people by giving them completely wrong information. However, some myths are ancient and involve rituals of the gods.
Lightning is complex in formation, protection, and myths. With lightning comes much danger, which still keeps scientists busy today studying the causes and effects of lightening. II. What is Lightning? Lightning is caused from the rising and lowering of air in a thunderstorm. The air movement separates the negative and positive particles.
Water and ice are also known to affect the electrical charge distribution. Lightning is the buildup and discharge of electrical energy between negative and positively charged areas. Lightning usually is ignited in the clouds or between the clouds and ground and is a strong electrical power. The average flash of lightning turns on a 100- watt light bulb for over three months.
Not only is the flash powerful, but also the air around the strike is hotter than the sun. The rapid heating and cooling of air caused by the strike results in a lightning channel shock wave known as thunder. Lighting occurs all over, the chance of being struck by lightning is 1 in 600,000. A lighting strike cannot only strike a person leaving them with an electrical shock or dead, but also can cause a fire. In the past 10 years over 15, 00 fires have been started by lightning.. Subtypes of Lightning There are two types of lightning discharges.
These are the CC (cloud to cloud) and CG (cloud to ground). These two discharges consist of different subtypes of lightning. These types of lightning are spider, bead, and ribbon. And rocket lightning. Spider lightning is a long lasting discharge, which usually exist along the cloud base.
The discharge is believed to be so long that it seems to crawl along the base of clouds, which is why the nickname for this lightning is crawler. Bead lightning is a discharge when the conductive part of lightning breaks up into balls of light. This process can occur quickly. Ribbon lightning occurs when the stroke moves sideways, either by wind or movement of the lightning channel. This pattern will break a bolt of lightning showing every stroke after another, similar to a ribbon. Finally, rocket lightning, which is uncommon.
This discharge moves vertically to and from the cloud; looking as a jet leaving its flame behind in the clouds. IV. The Damage and Protection from Lightning The danger of lightning can go to a great extreme from knocking out a radio communication, to destroying houses and killing people. When a lightning bolt makes contact with a person, fifty percent of the time it doesn? t result in death. The reason being is that lightning is such a high current of electricity that when it makes contact it hits and escapes the flesh in a matter of seconds.
Cardiac arrest, temporary blindness and deafness are just a few ways lightning can affect a human. To avoid things like this from happening, when a storm is close stay away from water, windows, and conductive materials (cars, airplanes, etc. ). When a tree is struck by lightning the liquids inside automatically turn into gas. This gas runs underneath the bark or near the center of the trunk.
As the result when the bark is struck, the tree will be missing a piece of various sizes. When the gas travels to the center of the trunk, the tree usually is destroyed or little is left. When a house is hit by the lightning an electrical current travels down conductive materials, usually around the outside of the house. This includes antennas, plumbing, and gutters. Any being touching metal, directly or indirectly, will be killed. Electrical appliances within the home are usually harmed or destroyed by peak currents and electromagnetic shockwave's. V. Myths of Lightning There are many myths on lightening that many societies have embraced, either modern or ancient.
Many say lightning never strikes in the same place twice, when the realty is that lightning has favorite sites, which it may hit many times during a storm. It is thought that if it is not raining then there is no danger of lightning. The truth is that lighting often strikes outside of rain and can occur as much as 10 miles away from rainfall. Rubber soles or shoes are known as protecting one from a lightening strike.
Against popular thought rubber soled shoes and tires provide no protection at all from strikes. The steel frame of a car gives more protection. Although many are injured from lightning strikes in a car, one is much safer inside a car than outside. An example of a myth is that people struck by lightning carry an electrical charge.
This myth can prevent a struck victim from receiving immediate attention. Another myth is that the early Greeks believe that lightning was the weapon of Zeus. Since lightning was the embodiment of the gods, any spot struck by lightning was regarded as sacred. The Moslems also linked lightning with gods, saying in the Koran that? He it is who show eth you lightning and launches the thunderbolts.? Scandinavians myths allude to Thor, which is the thunder and for of all demons.
Thor threw lightning bolts to his enemies. In the Hindu religion, the Maruts used thunderbolts as weapons. The Navajo Indians hold lightning in a pleasing light. They believe lightning has great healing powers; lighting is associated with wind, rain, and nourishing crops. The many different views of lightning within the different societies ancient and modern show the many emotions that lightning provokes; the emotions of fear and thankfulness. VI.
Conclusion Lightning is an interesting form in the earth's atmosphere. People will always have their own beliefs and theories of how lightning forms and why it approaches land and people the way it does. However, there is much research that explains how lightening is formed and why it happens when it does.
