![]() Additionally, the burning of vegetation releases nitrogen into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. When fire removes protective vegetation, heavy rainfall can contribute to increased soil erosion by water. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire is a significant process that influences ecological systems worldwide. įire, in its most common form, has the potential to result in conflagration, which can lead to physical damage, which can be permanent, through burning. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. If hot enough, the gases may become ionized to produce plasma. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. The flame is the visible portion of the fire. Īt a certain point in the combustion reaction, called the ignition point, flames are produced. ![]() The ignition and extinguishing of a pile of wood shavingsįire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.
