What Causes Lightning?

What Causes Lightning?

Lightning comes from charges inside a rain cloud.  They lift water droplets from the bottom of the cloud to the top.  Ice going down comes to water coming up.  When the ice meets water, it pulls off the water droplets.  It drags extra electric with it.  The bottom of a cloud has bad charges but on the top a cloud it has happy charges.  These charges become very powerful.  The gases in between a cloud act as an insulator in the middle of these charges.  Sometimes the charges can become too Powerful.  It overpowers the insulator. The cloud looks for the easy way to release its charges.  Lightning often happens between two clouds of inside a cloud Lightning can also travel from clouds to land.  Since the bottom of a storm cloud has a bad personality charge, it wants to flow to the top of the cloud.  The bad charges drops down like a rock in the water.  Meanwhile, the happy charged particles also want to meet the bad charges.  They ‘’reach up’’ from the land.  This makes a stream of positively charged air.  When the charges meet, lightning happens.  The extra electricity in the clouds jump to land.  When lightning strikes land, it heats up the air around it.  The air can get even hotter than the surface of our sun!  The hot air expands like bomb.  Then it shrinks back together. This makes a loud sound of thunder.  The air shakes in response.  This causes the rumbling sound that follows a loud first crack.  Lightning helps scientists tell what the weather will be.  They use tools or instruments to map where the thunder will travel.  This helps them follow dangerous weather.
