What is burning?

The video explains burning as a chemical reaction requiring fuel, oxygen, and heat. It describes how forest fires use trees as fuel and can be ignited by lightning or cigarettes. Once started, the fire generates its own heat to continue burning. The energy released is from stored energy in the trees, making it an exothermic reaction. Fire can be stopped by removing one of its elements: heat, oxygen, or fuel. Firefighters use water to cool fires or create fire breaks to remove fuel. Despite destruction, fires allow new growth as sunlight reaches seeds, aiding forest recovery.
