Question

What is lightning? Write any 2 advantages of lightning.

Answer 1

Hint: Lightning is an electrostatic discharge that occurs naturally and also visible. During the lightning two electrically charged regions in the atmosphere or ground equalize for a short time, causing the instantaneous release of a similar to one gigajoule of energy. Lightning and thunder both occur during thunderstorms. lightning is seen before one can hear the sound of thunder.


Complete step-by-step solution:
Lightning is a visible and natural discharge of electrostatic energy where different parts of the atmosphere equalize in charge. This causes insane fast energy known as lightning which can be very very dangerous. Thunder is heard after the lightning as thunder is created from a shockwave in lightning.
In general, There are three types of lightning: 1.cloud to ground, 2.cloud to cloud, and 3.cloud to air.
CLOUD TO GROUND LIGHTNING (NEGATIVE CHARGE)
Cloud to ground lightning is very dangerous. The ground generally consists of positively charged particles while the lower portion of violent storm clouds has negatively charged particles. since Opposite's charges attract, and lightning goes after positively charged particles. The most common cloud-to-ground lightning strike is a negatively charged strike.
CLOUD TO GROUND LIGHTNING (POSITIVE CHARGE)
When the lightning finds negatively charged particles on the ground and positive charges in the higher portion of a cloud overcome negative charges in the bottom of a cloud. This is when positive lightning happens. Positive lightning strikes do not generally happen but are more dangerous.
CLOUD TO CLOUD LIGHTNING
Cloud to cloud lightning occurs when a cloud with a negative charge finds a positively charged cloud and attracts each other. These do not strike the ground. They just traverse from cloud to cloud.

Advantages of Lightning:
Lightning helps dissolve the unusable nitrogen in the water that then creates a natural fertilizer. plants can absorb this through their roots.
Lightning produces ozone gas. Ozon is a vital gas in our atmosphere that helps cover the planet from rays of harmful ultraviolet.

Note:Lightning is a very dangerous thing. The safe places during lightning can be the iron-made house, buildings with lightning arrestors, and the metal-covered car that has a direct connection with the ground. On the other hand, The unsafe places can be the tall trees, telegraph and telephone post, wire net, or tall clay wall.
