Forest fires can spread dramatically, burning large numbers of trees in just minutes.

Burning is a chemical reaction that needs three things to happen: material to burn, called fuel, oxygen supply and a source of heat to ignite, or ignite, the fuel.

A forest fire uses trees for fuel and oxygen from the air.

The heat needed to set trees on fire can come from lightning or a cigarette butt.

But once established, the fire itself produces the heat necessary to burn more trees.

The heat and light released during the fire comes from the energy stored in the trees.

Chemical reactions that release energy are known as exothermic reactions.
