What is the scientific explanation of lightning?
In the initial stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground; however, when the differences in charges becomes too great, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we …
What causes lightning physical science?
Lightning is the result of the build up of electrostatic charge in clouds. Positive and negative charges separate, negative usually towards the bottom of the cloud, while positive goes to the top. After a certain amount of time, the negative charge leaps, connecting with either another cloud or even the ground.
What scientists dont know about lightning?
What don’t we know about lightning? The main problem is that we don’t know how a thundercloud gets the spark needed to initiate a lightning bolt. Years of experimental measurements from aeroplanes and air balloons have shown that the field is about 10 times smaller than what is needed to initiate lightning.
What causes lightning explain with diagram?
As the air rises, water vapour cools and forms a cloud. When air continues to rise, the cloud gets bigger and bigger. When the positive and negative charges grow large enough, a giant spark – lightning – occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger.
How do you describe lightning?
Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. When the opposite charges build up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning.
Why do lightning conductors have spikes?
Explanation: Lightning rods are pointed so a charge will be concentrated at the end. If the rod had a round end the charges would spread equally around its surface. As long as the air is prevented from ionizing it won’t conduct the lightning bolt.
Does lightning make sense?
But as for how all that happens — well, it just doesn’t make much physical sense. There are three big questions needing answers, said Joe Dwyer, a leading lightning physicist based at the Florida Institute of Technology. “First, how do you actually charge up a thundercloud?” Dwyer said.
Can we reproduce lightning?
It is entirely possible to create static electricity, and even lightning using this method. This lightning is generated using capacitor banks (not rubbing stuff together, the way natural lightning is created) and is feeble by comparison to the real thing. Also, it isn’t used to generate power.
What is lightning short answer?
Lightning is a very powerful electrical discharge made during a thunderstorm. The electric current makes the air very hot. The suddenly heated air expands very quickly, which causes thunder. Sometimes lightning happens between clouds. If it goes from cloud to ground, it can strike a person.
Is there such a thing as xenoglossy?
Xenoglossy is the alleged speaking of a language that is entirely unknown to the individual. The person speaks the language fluently, even though he/she has never heard it before. In my previous article, about xenoglossy, I had written about how it cannot be explained by the language acquisition theories.
Where does the energy of lightning come from?
Lightning explained. Lightning is a large-scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the Earth’s surface. On discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°C.
What are the conditions needed for Lightning to occur?
Conditions needed for lightning to occur It is the formation and separation of positive and negative electric charges within the atmosphere that creates the highly intensive electric field needed to support this natural spark discharge that is lightning.
When did Charles Richet invent the term xenoglossy?
Charles Richet coined the term xenoglossy in 1905. Xenoglossy (/ˌziːnəˈɡlɒsi, ˌzɛ-, -noʊ-/), also written xenoglossia (/ˌziːnəˈɡlɒsiə, ˌzɛ-, -noʊ-/), sometimes also known as xenolalia, is the putative paranormal phenomenon in which a person is able to speak or write a language he or she could not have acquired by natural means.
