How Does Lightning Form
What Creates the Bright Light in the Clouds during Lightning
The atmosphere usually acts as an insulator and doesn’t allow the lightning to flow anywhere else except within the cloud. This limits the electric charges, along with the light produced by them, within the boundaries of the cloud, illuminating the entire cloud.
How Does Lightning Work to Strike the Earth
When the charges developed in the cloud are strong enough, they may break the insulating property of the atmosphere and make electric current flow down to the earth that has a positive charge, which travels back to the sky as a brighter spark. Usually, the positive charge on the ground develops on tall structures such as buildings, trees, electricity poles, etc. The downward and upward flows of electric current are cumulatively seen as lightning.
What Makes the Loud Sound Along With Lightning
A high temperature (53,540 degrees Fahrenheit, about six times the temperature of the sun) is produced by a single bolt of lightning. The air through which the spark passes becomes excessively heated and expands rapidly producing a loud sound that we hear as thunder. Lightning may cause death or severe injury if it strikes a person. Hence, it is important to take adequate safety precautions during lightning. Stay away from electrical appliances, open doors and windows, water bodies, open fields and remain indoors.
