What is a bushfire?

Answer 1

Bushfires are fires which occur in the Australian bush, usually native bushland, which quickly spread out of control. They may last a matter of hours, or up to three weeks, as in the case of the deadly 2009 "Black Saturday" bushfires.

Bushfire is also the general term for any grassfire that occurs in rural areas.

Bushfires are common in Australia's southeast up to the Queensland/New South Wales border during the summer months, and again further north around Rockhampton. They also occur regularly in the southwest of Western Australia. The intensity of bushfires is increased by dry vegetation, often after a period of heatwave, together with strong, gusting winds, and absence of precipitation. Hilly or mountainous terrain is more prone to bushfires than flat land, where bushfires can be more easily controlled.

Statistics indicate that most bushfires are caused by lightning strikes. Bushfires are, unfortunately, also commonly caused by man's activities, whether arson or unintentionally lighting the fires such as by tossing cigarettes out of car windows, or not extinguishing campfires properly. Faulty power lines are also often a cause. Sparking and arcing from these powerlines easily ignites into bushfires.

Answer 2

A bushfire is a wildfire that occurs in areas of grass, brush, or forest. These fires can spread quickly and be difficult to control due to the abundance of fuel in these environments. Bushfires can have devastating effects on ecosystems, wildlife, and human communities.
