Question

The process of electric discharge between different clouds causes __________

Answer 1

Lightning:

1. The occurance of lightning depends on the atmospheric conditions.
2. It needs a weather in which moisture-laden warm air near the earth rises rapidly.
3. As the moist air rises, it collides with the other drops of moisture and air molecules and so lose or gain electric charges by friction.
4. Usually, the moisture drops become positive and the air molecules negative.
5. When moist air becomes cold enough, it condenses to form a cloud.
6. The lower part of the cloud usually becomes negative and upper most part of the cloud becomes positive.
7. The sudden movements in the cloud cause this charge to discharge in a flash of lightning to another cloud or the earth

Hence, the process of electric discharge between different clouds cause lightning
