Question

why is thunder produced by thunder storm ​

Answer 1

Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder.

Answer 2

$\mathbb{\huge{\pink{ANSWER}}}$

Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. However, the grumbles and growls we hear in thunderstorms actually come from the rapid expansion of the air surrounding the lightning bolt.
