Dec 3, 2021 · We spoke with NC State professor Joseph Roise, who studies wildland fire behavior and prevention, to gain a better understanding of how wildfires like the one at Pilot Mountain State Park start and spread. Here’s what we found out.
A fire requires fuel to burn, air to supply oxygen, and a heat source to bring the fuel up to ignition temperature. Heat, oxygen and fuel form the fire triangle. Firefighters often talk about the fire triangle when they are trying to put out a blaze.

Apr 30, 2024 · The Short Answer: Wildfires are uncontrolled fires that spread quickly, destroying homes and the environment nearby. Conditions in the weather and environment—such as drought, winds and extreme heat—can cause a fire to spread more quickly.
A wildfire is an uncontrolled fire in an area of combustible vegetation that occurs in the countryside or a wilderness area. Other names such as brush fire, bushfire, forest fire, desert fire, grass fire, hill fire, peat fire, vegetation fire, and veldfire may be used to describe the same phenomenon depending on the type of vegetation being burned.
