FOREST FIRES
A forest fire is an uncontrolable fire occuring in nature, specifically forests. In lots of cases, forest fires can become so large that it can take a long time for fire fighting crews to gain control of the fire. This can sometimes result in massive destruction. There a number of forest fires from year to year, and some can last months. Climate is a big part of forest fires. They usually happen during the spring and summer, when it is the most dry. Weather conditions such as precipitation and wind determine the size of the forest fire.
It is estimated that 9 out of 10 forest fires are caused by humans. The most common cause of these fires is the use of open flames and disposable barbecue grills. Even something as simple as a cigarette that is not extinguished that cause a forest fire. Some forest fires also start because of drowned power lines, sparks for trains, sparks from roads, and sparks from tools and machines being used in forests. Lightning strikes cause natural forest fires.
Fun Fact:
There are 3 types of forest fires: A ground fire, a surface fire, and a crown fire. Ground fires are slower burning fires; they burn by glowing combustion. Ground fires burn in the roots under the tree. Surface fires burn on the surface of the ground. They burn dry leaves, broken twigs and branches (anything on the ground) and spread quickly. Crown fires burn with huge flames, intense heat and lots of power. The burn from tree top to tree top and also spread very quickly with wind and heat.
