'''Thunner''' is the soond caused bi [[lichtnin]]. Dependin on the distance an naitur o the lichtnin, thunner can range frae a sharp, loud crack tae a lang, law rumble (brontide). The sudden increase in [[pressur]] an [[temperatur]] frae lichtnin produces rapid [[Thermal expansion|expansion o the air]] surroondin an within a bolt o lichtnin. In turn, this expansion o air creates a sonic shock wave, seemilar to a [[sonic boom]], which produces the soond o thunner, eften referred tae as a ''clap'', ''crack'', or ''peal o thunner''.
