WHAT IS THUNDER ?
Thunder is actually the sound of Lightning. As lightning connects to the ground from the clouds, a second bolt of lightning using the same path, will return from the ground to the cloud, heating up the air around it.
The compressed air of heat explodes outwards from the path, sending out a shock wave of compressed particles in every direction. These waves of compressed air create a loud, booming burst of noise.
