Why lightning occurs in an instant, but the resulting thunder rolls and rolls and lasts a while

So yesterday we had some thunderstorms where is wasn’t raining yet, but I could see and hear the lighting & thunder. I layed down on our lanai just to enjoy the show. Enjoying counting the seconds between lighting flash and the thunder to determine distance. And I saw this one bolt of of lightning, really bright. Starting counting seconds, only got to 5, before the thunder exploded. So about a mile away. But after the initial bang, the thunder continued booming a rolling across the sky, it must have lasted 10 seconds. Seems like it should should just boom once.

Sound is a wave. Waves bounce off of things. In sound’s case, it will bounce off of pretty much anything solid. Trees, grass, buildings, rocks. you name it.

One loud bang will create billions of tiny reflections that add together to produce a rumble.
