What effect does hot air and gases have on vegetation as the fire approaches?

When a wildfire approaches, the hot air and gases produced by the fire can have significant effects on vegetation. The correct response highlights that these elements can dry and preheat the vegetation. As the temperature rises due to the proximity of the fire, the moisture content in the plants decreases through the process of evaporation. This drying effect makes the vegetation more susceptible to ignition, as drier materials catch fire more easily. Furthermore, preheating occurs when the intense heat from the fire begins affecting vegetation even before the flames come into direct contact. This increases the likelihood of combustion once the fire reaches that area, as the plant materials have already been conditioned to burn more readily.
