What term describes the movement of fire from one location to another?

The term that describes the movement of fire from one location to another is "Fire Spread." This concept encompasses the ways in which flames and heat can transfer across different materials and environments, allowing the fire to grow and extend beyond its original source. Fire spread can occur through various mechanisms such as convection, conduction, radiation, and even the presence of combustible materials in the path of the fire. Understanding fire spread is vital in fire investigations as it helps in determining how fires develop, which influences both the fire's growth pattern and the investigation of the incident.

In contrast, fire propagation typically refers to the processes that allow fire to sustain and increase in intensity, rather than the physical movement to other areas. The term "First Fuel Ignited" indicates the first material that caught fire but does not describe the dynamics of fire movement. Lastly, "Flame" simply refers to the visible, gaseous part of fire but does not encapsulate the concept of how fire transitions from one area to another. Thus, "Fire Spread" effectively captures the essence of the movement of fire in various scenarios.
