In the picture
- An ice crystal inside the turbulent cloud
- A round water droplet colliding with the ice crystal
- A cluster of bright sparks near the lower cloud
- A cluster of bright sparks near the upper cloud
Examples
- A balloon rubbed on your hair then sticking to a wall.
- A crackling spark when you touch a metal door handle after walking on a carpet.
Key takeaways
- Colliding ice and water in a storm cloud move electric charge apart.
- Different parts of the cloud can build up different charge, which can lead to lightning.
