There is an accumulation of positive charges near the ground
The ground is neither positively charged nor negatively charged
- When a charged cloud comes close to another cloud, it induces an opposite charge in the second cloud.
There is an accumulation of negative charges near the ground

Which of the following shows the characteristics of lightning?
It happens through the process of electric discharge between two or more clouds or between clouds and the earth.
- Positive charges are accumulated at the bottom of the clouds.
