-
Fire Triangle
Oxygen - 16% is necessary,
-
-
Distribution
95% occur due to human activity, but are the result of natural cycles: Dryness, Rainfall, and Storm. Lack of fires in deserts, due to lack of vegetation, Savannahs are key locations, for they are dry but still contain plants
Expansion
-
Firebrands - fireballs that fly to other places, spreading the fire
Conflagration: As heat rises, there is a volume of low pressure, due to this, oxygen rich air moves over to reach balance which adds more oxygen to the fire, this is a positve multiplyer effect.
Suitable Conditions:
If the humidity is at 15% it is low risk, but at 7% it is at high risk.
-
Fire results in creation of weather, which can aid tropical storms.
