What happens as soon as lightning strikes a beach? we take a look at ten interesting facts that you can not know around lightning.
You are watching: How wide is a lightning bolt
1. The speed of lightning
While the flashes we view as a result of a lightning strike take trip at the speed of irradiate (670,000,000 mph) an actual lightning strike travel at a comparatively gentle 270,000 mph.
This way it would take around 55 minutes to take trip to the moon, or around 1.5 secs to get from London come Bristol.
2. As soon as lightning strikes a beach
When lightning strikes sand or sandy soil, the fuses together the grains to develop a tiny glass-like tube well-known as a fulgurite.
They space not just prized through collectors, they are additionally of an excellent scientific worth in demonstrating past incident of lightning storms.
3. The most lightning-struck location in the world
Lake Maracaibo in Venezuela is the place on earth that receive the most lightning strikes. Massive thunderstorms occur on 140-160 nights every year through an typical of 28 lightning strikes per minute lasting approximately 10 hours at a time.
That's as many as 40,000 lightning strikes in one night!
4. Helicopters reason lightning
Recent study from the Met Office revealed that helicopters can reason an secluded lightning strike. If flying, the helicopter repurchase a an unfavorable charge, so if it flies close come an area the is positively fee (e.g. Hail or the base of a cumulonimbus cloud) that can trigger a lightning strike. Investigating and predicting helicopter-triggered lightning strikes
5. 1,400,000,000 strikes every year
Lightning is among nature's many recurrent and common spectacles. Roughly the world, there room over 3,000,000 flicker every day.
That's around 44 strikes every second.
6. Lightning destroys trees
Trees can regularly be damaged by lightning strikes. Once lightning hits a tree, it typically travels just below the tree's bark where there is a class of sap and water.
This layer i do not care instantly heated and also expands causing the bark to it is in blasted turn off the tree and also sometimes splitting the wood.
7. But it can aid plants grow
While nitrogen is in the air all about us, for plants to have the ability to absorb the (a process critical for their growth) they rely on a process called Nitrogen fixation.
Although lot of this process is excellent by bacteria and also algae, the too much heat of a lightning strike reasons nitrogen to bond through oxygen to produce nitrogen oxides which combine with moisture in the wait to fall as rain and water plants v nitrate-rich water.
8. The width of a thumb and also hotter 보다 the sun
While the intensity of a lightning strike deserve to make them appear as thick bolts throughout the sky, the actual broad of a lightning bolt is only about 2-3 cm. The average length of a lightning bolt is around 2-3 miles.
The charge carried down this tiny channel is so intense that the temperature that the lightning reaches 30,000 °C - that's five times hotter 보다 the surface of the Sun.
9. Volcano lightning
While lightning storms are exceptional in their very own right, they don't rather compare come the spectacle as soon as volcanic eruptions cause lightning strikes.
When an eruption occurs, earth and also ash space thrown right into the wait in a gigantic plume, colliding to produce an electric charge. In the same method as regular lightning, the imbalance in between the plume's electric charge and also the fee in the environment leads to lightning strikes.
10. Counting lightning
To phone call how much away a thunderstorm is, merely count the number of seconds between the speed of lightning and also the boom of thunder the follows. Divide this number through five and also this speak you how many miles far you space from the storm (or divide by three for the street in kilometres).
Did friend know, till the so late 18th century that was believed that ringing church bells repelled lightning so many church bells boring the inscription fulgura frango, meaning 'I follow lightning'.
During a thunderstorm, bell ringers would certainly run come the bell tower to ring the bells. However, a high tower with a steel bell remained in fact around the worst place to be.

Between 1753 and also 1786 in France, 103 bell-ringers were struck through lightning and also killed, leading to the custom being banned.
