  1. 1. What’s up with the weather? Topic: Forest fire By: Jiaming Mei
  2. 2. Definition-• Forest fire: an uncontrolled fire in a wooded area.
  3. 3. Vocabulary-Evacuees Conflagration Surface firesAcres Extinguishing FuelIgnited Lightning CampfiresDevouring
  4. 4. Causes/EffectsCause- Forest fire usually caused Effects- Environmental: Whenby human or lightning. Human- the fire spreads through the forestcaused fires are started by people it kills the plants and the nutrientwho are careless with their inside the plants that the animalscampfires. Lightning-caused fires eat. Also, there will be more airare lightning strikes a tree, and the pollution on this worst.tree begins to burn, with flamesspreading to another trees as Economic: Can be damage to bothworst. coal and national economics can be just as terrible as the environmental destruction and the potential for loss of life. Social: Forest products would be destroyed, such as wood, food and medicines.
  5. 5. Map-• The map shows the occurrences of forest fires in the world over a 10-day period. The red part in the bottom of the map indicated places that forest fires happen frequently due to high temperature , while the northern part of the earth has less forest fires.
  6. 6. Graph-50 Forest fire numbers of 2010 on the world45403530 Number of fires25201510 5 0 Countries
  7. 7. Support Evidence-• This data shows the U.S. forest fire hot spot during the period of 2002-2012, occur the map in western part of the country during the summer months and are caused by lightning, there are three different graphs indicated many causes, trend of fire, and largest fires by which locations. The biggest reason is the occurrence of fires caused by lightning, the number is close to 50k. Then, the largest fires most occurred in Wallow.
  8. 8. Support Evidence-• This bar graph shows the wildfire activity during years of 2000- 2012. These figures represent annual acres burned per fire. Obviously, the fire in 2012 was the worst among those wildfires from 2000 to 2012, which burned more than 500 acres.
  9. 9. Prevention List of the ways to prevent forest fires.• Smoking should not be done while moving from one place to another in forest land.• Clear the area around the burn pile of any flammable debris.• Attend the fire until it is completely out.
  10. 10. Conclusion• The forest fire can be defined as uncontrolled fire on lands covered all by timber, grass, grain, or other flammable vegetation. Forest fire can be caused naturally or by humans. Three conditions are needed in order for a forest fire to ignite, which are fuel, oxygen and a heat source. For this research, I already gathered lots of evidence through the Internet to support my findings. When I researched my topic, I found that lots of natural disasters were able to prevent from happening. For instance, forest fire is very important for public safety. Preventing these fires from spreading across large regions is crucial. However, in fact, many acres of forest fires are burned because of human carelessness. We must learn all about fire prevention. Recent research has concluded that forest wildfires in western United States are becoming larger and more frequent. With the size of the fire, annual high severity fire will change with the weather for temperature rise. However, fire trend in forest fire must necessary to improve well environment. If this pattern continues for the next 100 years, we can expect our climate scientists to prevent any of this types natural disaster.
