Why Do Forests Sometimes Burn All at Once?

Imagine a big bonfire. It starts small, but if it has enough fuel, like logs and leaves, and the wind helps carry the fire from one spot to another, it can suddenly become huge. That’s what happens in forests sometimes: when conditions are just right, a fire can spread so quickly that it feels like the whole forest catches fire at once.
