Thunder

"THE history of the tale of terror is as old as the history of man. Myths were created in the early days of the race to account for sunrise and sunset, storm-winds and thunder, the origin of the earth and of mankind. The tales men told in the face of these mysteries were naturally inspired by awe and fear."--The Tale of Terror (1921) by Edith Birkhead |

Thunder is the sound 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 (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave, similar to a sonic boom, which produces the sound of thunder, often referred to as a clap, crack, or peal of thunder. The distance of the lightning can be calculated by the listener based on the time interval from when the lightning is seen to when the sound is heard.
