Transcript of Different types of bushfires

Bushfires
How bush fires start
50 000 bushfires occur each year. Bush fires effect lots of people’s homes, health and their living. A Bushfire has a big effect in the environment and everything it burns down. When a bush fire burns down a tree, the tree will grow back to be a stronger tree than it was before. A bushfire is when a spark goes out of control and starts a massive fire that will burn down everything in its path.
Bushfires have been a part of Australia for millions of years. The effects of a bushfire are unbelievable. They leave hundreds of people homeless and they also take the lives of many people. Bushfires would leave lots of sadness on many people because it is a really sad time when you have lost your home and lost your family members. The bush fire leaves a big effect on the land and the nature. The ground becomes all burnt, dry and black. The air becomes smoky and the trees are burnt down and broken. These are the effects that a bush fire leaves on the earth and the people.
Introduction
During a bush fire there are many people that help. There are fire fighters that help put out the fire. There are also the CFA, SES, and the MFB that help put out the fire as well. At the end of a bush fire lots of people help like the community who all come together and all help each other. During Black Saturday, the community put lots of money together to get their town back together again.

There are many different types of bush fires.
For example:
Forest fires: Forest fires normally start from eucalyptus trees because they are oily, so on hot and dry days it would be easy to catch fire to them.
Crown fires: Crown fires are when the top of a forest catches on fire. The reason most crown fires happen is because at the top of trees it tends to be drier than the rest of the tree. When the sun shines on it and it’s a hot day it could cause a spark.
Man Made fires: Man made fires can start from lots of different ways. One of the ways that it could start is by lighters and people lighting cigarettes. Cigarettes are especially dangerous. If you leave them in a dry area and you haven’t burnt it out; it could catch fire easily and if it was on a dry, hot day.


How bushfires start - Weather


How bush fires start- Weather
Bushfires start from dry areas such as places that have not had rain for a long time. In these areas, it is easy to burn objects. This usually happens in the hotter months because in winter it’s harder for a bushfire to start. This is because it’s a wet environment and the fire won’t catch on to objects. If a Bushfire was going to start, the main thing you would need is the hot weather because there would be no use trying to make a fire on a wet, cold and damp day.


How bushfires start - What you need


A fire needs Air, Heat and Fuel to make a fire. Without of all of these together, the fire will not be successful. But not every fire starts with just air, heat and fuel. It would also need a spark. Because without that spark it would be difficult to start the fire. The spark could be anything for example a cigarette, a lighter or solar energy. But still it would always depend on what the weather is because that plays a big role in fires.

Map of Australia
On the 7th of February 2009 the tragedy of Black Saturday started. The day was 35 degrees and higher. The high pressured wind from the Tasman Sea had helped the fire to start. The heat and wind were pushing against each other. During this time there was a drought so the fire got bigger and reached 1200 degrees. This fire had left 200 people to die and 7000 people were left homeless. The fire was traveling 150km per hour and 150,000kw per square metres of energy was being wasted.
Climate change plays a big role in bush fires. Therefore it makes everything much more risky because the weather becomes warmer faster. In winter, bushfire are very unlikely to happen because everything is wet. In winter when it’s too damp and wet for a large disaster. So the fire could possibly not catch on to anything and burn it.

In conclusion, bush fires are very dangerous and affects lots of people and their homes. Bush fires would usually occur in hot and dry weather. As this report has shown bush fires can start in many different ways such as Lightning, Sparks and Man-made fires and has devastating effects, where people and animals may die. However on a positive, the community comes together and helps so they become a stronger and closer.
