What are the phenomenon of thunder and lightning?
Lightning is a discharge of electricity. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder.
What causes the sound of thunder in lightning?
Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. However, the grumbles and growls we hear in thunderstorms actually come from the rapid expansion of the air surrounding the lightning bolt.
Is thunder a phenomenon?
Thunder and lightning is a weather phenomenon which occurs when the atmosphere is unstable.
What does it mean if you see lightning and hear thunder at the same time?
positive lightning
The rapid expansion of heated air causes the thunder. Since light travels faster than sound, the thunder is heard after the lightning. If you see lightning and hear thunder at the same time, that lightning is in your neighborhood. Lightning from this area is called positive lightning.
What is lightning phenomenon?
Lightning is a natural phenomenon which develops when the upper atmosphere becomes unstable due to the convergence of a warm, solar heated, vertical air column on the cooler upper air mass. This same updraft gives rise to an electric charge separation which ultimately leads to the lightning flash.
What is the sounds of thunder?
The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt. In turn, this expansion of air creates a sonic shock wave, often referred to as a “thunderclap” or “peal of thunder”.
What is the sound of thunder in words?
Words associated with the sounds thunder makes and are onomatopoeic are “clap,” “boom,” “crack,” “rumble,” and “crash.”
What is the sound of lightning in words?
As an example, you can use “rumble” or “boom” for the thunder, the sky was lit up by lightning. Sometimes you can use an onomatopoeia (description of sounds with words like ‘boom’, ‘clack’, ‘ buzz’, etc)
What does it mean when thunder is really loud?
If the thunder sounds more like a rumble, the lightning was at least several miles away. The loud boom that you sometimes hear is created by the main lightning channel as it reaches the ground. Remember, if you can hear thunder, chances are that you’re within striking distance of the storm.
Which of the following best describes the relationship between lightning and thunder?
Which of the following best describes the relationship between lightning and thunder? Lightning ALWAYS produces thunder, but you hear the thunderclap after you see the lightning because light travels much faster than does sound.
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.
Is thunder heard before the flash of lightning?
Thunder and lightning all occur due to the release of energy – thunder is a soundwave, and lightning is the emission of electromagnetic energy. The reason we see a flash of lightning before hearing thunder is because light travels faster than sound.
What causes the sound of Thunder?
Thunder is caused by lightning. Thunder is the sound caused by rapidly expanding gases a channel of lightning discharge. Lightning has enough energy to heat the air up to 18,000 degrees Fahrenheit. This causes a rapid spreading of the air, creating a sound wave heard as thunder.
How loud is the sound of Thunder?
A thunder is considered very loud and hurtful to the human ear. It is approximately 120 decibels, maybe little less that a chainsaw according to scientific measurements. add a comment.
What are the effects of lightning and Thunder?
Sound Effects of Thunder. Thunder occurs as an acoustical effect of high temperature and pressure during a lightning storm. The change in pressure affects the human ears, which is how thunder is heard. The highest pressure in a storm happens a few inches away from the origin of the lightning strike, causing a rumbling noise.
