What color lightning is the strongest?
White – this is by far one of the most dangerous color of lightning due to the fact that this type of lightning is the hottest. This color can indicate a low concentration of moisture in the air as well as a high concentration of dust in the air.
Why is the lightning green?

Do cars get struck by lightning?
NO! Like trees, houses, and people, anything outside is at risk of being struck by lightning when thunderstorms are in the area, including cars. ... The lightning will then pass through the vehicle's outer metal shell, then through the tires to the ground.
How is lightning made?
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
Does lightning come before thunder?
A person on the ground sees the lightning flash before hearing the thunder because light at a speed of around 300,000,000 meters per second travels much faster than sound which moves at 340 meters per second. ... Lightning always comes with thunder.
Is Red lightning real?
Yes, red lighting or red sprite is real. However, it is not so common as usual lighting bolts, and it is not easy to observe or film. ...

Why are cars safe in lightning?
Cars are safe from lightning because of the metal cage surrounding the people inside the vehicle. This may sound counter-intuitive because metal is a good conductor of electricity, but the metal cage of a car directs the lightning charge around the vehicle occupants and safely into the ground.
Is lightning hotter than the sun?
Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
