Geographical processes
Weather is a major contribution to the starting of bush fires, the hotter, the drier the more
likely it is for a bushfire to start and spread. The wind will reduce humidity and cause ongoing bushfire
to spread more rapidly. Often these winds are brought from the dessert areas of Australia. Therefore the geographical
process tends to be that bush fires are more common inland then on the coast areas where it is a wetter environment.
Bush fires will move faster in hill areas. For every 10 degrees of slope, the speed of the bushfire will double as it travels up hill.
Another way that bush fires can be started is by people whether they deliberately lighting them or whether it is accidental. Some examples of accidental bush fires include: unattended or improperly lit camp fires, agricultural burns that are not being monitored properly, sparks or heat from electrical equipment or machinery, car exhausts or discarded cigarettes, litter suchas glass bottles thrown into heavily grassed areas.
In some cases the fires are not always lit accidentally sometimes the fires may be lit on purpose by aronist these are people who love to light fires. This can destroy thousands of acres of land. Arson is the second most common way of combustion and 25% of fires are lit this way.
Many things influence the ignition of a bushfire. Once the fire has begun it can either be dealt with or can spiral out of control. If the fire was to spiral out of control it can cause a greater impact on the environment.
Some factors include:
-Lack of rainfall
-Wind
-Humidity
-Temperature
