Lightning is a natural phenomenon that can cause large-scale destruction of life and property. We can predict them to a certain extent but not perfectly. It can be explained by using the concept of production of electric charge by rubbing.
When a thunderstorm develops, the air currents move upward whereas the water droplets move downward. This movement also causes a separation of positive and negative charges on the clouds. The negative charges accumulate near the lower end of the cloud while the positive charges collect near the upper edge. Also, a positive charge accumulates on the ground as well.
As these charges accumulate, it reaches a stage where it is impossible for air (a poor conductor of electricity) to resist the attraction between the positive and negative charges. When these charges meet, they create streaks of light and loud sounds. The charge gets discharged. This discharge can occur between two clouds or between clouds and earth. This causes lightning.
