What is the term for the outer edge of a wildfire where active combustion occurs?

• A. Fire front
• B. Burning edge
• C. Flame front
• D. Hot zone

Answer: (B)

The outer edge where active combustion is occurring is called the fire front. This boundary marks the moving edge between burned and unburned fuel, where heat from the flames preheats and ignites new fuel as the fire advances. The hot zone describes the area of intense heat around the fire rather than the edge itself, and while flame front can refer to the line of flames, the standard term used in wildfire behavior is fire front. So, the edge of active burning is the fire front.
