Fire behavior refers to how fire reacts to its environment, including factors like fuel, weather, and topography. The type of fuel, such as grass or wood, affects how quickly a fire spreads. Weather conditions, like wind and humidity, can either help a fire grow or slow it down. Additionally, the landscape plays a crucial role in fire behavior. Steep slopes can cause flames to rise faster, while valleys may trap heat and smoke. Understanding these elements helps firefighters and researchers predict how a fire will move and develop, which is essential for safety and effective firefighting strategies.
