Question

Does lightning come from the ground? I have heard that lightning comes from the ground up. But when it strikes something on land, it's the top of that object that gets destroyed.

Answer 1

Lightning does not come from the ground. It comes from the sky, mostly during thunderstorms. Watch the sky the next time you see a thunderstorm. You might see the lightning strike.

Answer 2

I don't know the ratio between the modes, but lightning can consist of an electric current from cloud to ground, or from ground to cloud, or between two clouds.
