Which of the following are considered the four factors of fire behavior?

The correct answer highlights the four critical factors that influence fire behavior: weather, topography, fuels, and time. Each of these elements plays a significant role in how a fire starts, spreads, and is controlled.

Weather encompasses not only temperature and humidity but also wind patterns and atmospheric pressure, all of which are crucial in determining how a fire behaves. Topography refers to the physical features of the landscape, such as slopes and elevation, which can affect the movement of fire by altering wind patterns and creating natural barriers or pathways for fire spread. Fuels are the materials that burn, which include not just vegetation but also other combustible materials in the area. Time is important as fire behavior can change throughout the day and night, influenced by the weather and environmental conditions.

Understanding these four factors gives firefighters the knowledge they need to predict fire behavior and take appropriate action in managing and controlling wildfires effectively.
