Explanation: 

Detailed explanation-1: -Weather conditions such as wind, temperature, and humidity also contribute to fire behavior. Wind is one of the most important factors because it can bring a fresh supply of oxygen to the fire and push the fire toward a new fuel source.

Detailed explanation-2: -A lot of factors influence fire intensity, such as weather conditions; amount, size, and moisture content of the fuel (i.e., fuel load); plant chemistry (e.g., conifer needles that emit flammable terpenes contribute more to fire intensity than green maple leaves); and topography.

Detailed explanation-3: -Fire spread depends on the principal methods of heat transfer: conduction, convection, radiation and direct burning.

Detailed explanation-4: -Use wildfire-resistant building materials and landscaping. Direct how communities develop in wildfire-prone areas with plans and regulations. Be ready for wildfires with community alerts, evacuation routes, and family plans. Address the social and economic vulnerabilities of people in the community.
