    wildfires are large uncontrolled inferno’s that burn and quickly spread through wild lands scapes

    types of wildfires may include forest
    , brush , and peatland fires, depending on the land scapes affected

    Wildfire require three components known as the fire triangle .

    A heat source , fuel and oxigen .
    heat Source such as the Sun a hot bolt of lightening or smolderning match can supply enough heat to spark a fire .

    That spark then turns in to flames when fuel or any flamable material is present .

    Dry , dead grasses , leaves and trees are common fuels for whildfires but so are living vegetation called green fuels .

    Pine trees ever green contain flamable oils that can burn when expose to a heat sorce .

    As the fuel burns the resulting flames feed and thrive off of oxygen

    When air movement or wind occurs ، not only is more oxygen supplied to the fire but it may also help transport and spread the flames .

    since wild fire occure outdoors , they have a nearly endless supply of oxygen from our atmospher to burn .

    Many wildfires are the result of natural causes .

    A warmer climate and weather patterns like , EL Nina can creats the hot , dry conditions necessary for fires to erupt
