Thunder and lightning are natural phenomena that happen during storms. Lightning is a sudden flash of electricity caused by the buildup of electrical charges in clouds. When these charges become too strong, they discharge as lightning, which heats the air around it rapidly.
The rapid heating and expansion of air cause the sound waves we hear as thunder. Thunder always follows lightning because light travels faster than sound. These events are both powerful and dangerous, but they also play an important role in the Earth’s weather systems. Shutdown123
