Thunder is caused by Lightning. depending on the nature of the lightning and distance of the listener, thunder can range from a sharp, loud crack to a long, low rumble. The sudden increase in pressure and temperature from lightning makes very fast expansion from the air surrounding and within a bolt of lightning.
This expansion of air creates a “sonic shock wave” which produces the sound of thunder; often known as a clap, crack. The distance of lightning can be decided by the the person hearing the thunder and lightning based on to the time when the lightning is seen, to when the sound is heard! Thunder and lightning can go on for days it can travel for kilometers!
Thunder firstly occurs from strong: winds, rain, and hail. Thunder and lightning doesn’t stay in one place at a time, the clouds keep up with the wind current. Sometimes thunder occurs before rain or hail even starts! They can occur inside warm, moist air masses. The clouds form thunder storms but sometimes clouds form a thunderstorm without them raining or hailing because they are already moist enough to begin one.
Thunder and lightning is very dangerous. lightning can strike and kill you and also start fires. Lightning can hurt anyone and kill anyone in just seconds. Like the time when a wave of thunderstorms and wind blew near the south of America last year, killing at least 16 people. Thunder and lightning is very dangerous and is something that must be avoided because it can lead to death. So keep an eye out for lightning striking houses and buildings etc! There has been a history of terrible events caused by thunder and lightning killing people and destroying things.
So in conclusion thunder and lightning is pretty amazing. It is caused by nature and bad weather and is to be avoided at all costs because it is very deadly and dangerous.
