Explain the main elements of the fire triangle?
For the fire triangle to work and for the fire to spread and develop. You need 3 things fuel, air and heat. It needs fuel to be able to survive as well as air so it doesn't suffocate. The heat is from the flames and bushfires are mainly put out through water and the cooling.
How Climatic Conditions Enhance A Bushfire.
Climate Conditions: Humidity, Lack Of Rainfall, Wind And Temperature
Humidity: Causes fuel to dry out and become flammable
Lack of rainfall: Leads to dry vegetation \
Air: Provided the oxygen to keep the fire burning as well as blowing embers
Temperature: Hot air lowers moisture content of vegetation
Characteristics of Australian Vegetation

Characteristics of Australian Vegetation
- Eucalyptus litter is coarse and decays slowly, ensuring that after several years there will be an abundant build-up to carry the next fire.
- The bark of many species is flammable and loosely attached to the trees, making ideal firebrands to carry fire across natural barriers.
- The green leaves contain highly flammable oils and resins that act as a catalyst to promote combustion before the leaves are fully dry.
