by Ron Kurtus (updated 30 May 2023)

Take this Mini-Quiz to check your understanding of the lesson material.

1. How do the electrical charges in a cloud become separated?

Opposite charges repel, moving them apart in the cloud

Winds in the cloud blow the lighter positive particles upward, away from the heavier negative particles

The Earth's magnetic field separates the charges

2. What starts the electrons moving through the air?

The air ionizes due to the strong electric field

Extreme turbulence in the clouds move the electrons through the air

Thunder shocks the electrons with a sonic boom

3. What is the greatest benefit of lightning?

It helps to naturally fertilize the soil

It kills many people and starts forest fires

Lightning is fun to watch

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Power can be awesome
