Wildfire in Fort Mcmurray
Wildfire in Alberta
Fires are very unpredictable, they can travel at speeds of 23 kilometres per hour when whipped up by the wind as long as there's fuel. Climate change had lead to an increase of wildfires in the region.
The fire burns at about 800 to 1,000 C.
This gives you an idea of just how big this wildfire is. In only one night the fire more than doubled in size.
Authorities are not sure of what started the fire but it continues to grow.
To stop the fire we need to know where it will go next. A fire needs three things to sustain itself, fuel, heat, and oxygen. To stop the fire you need to remove one of these. This can be done by creating a backfire which is a fire that burns the fuel ahead of the fire you're trying to fight so that it doesn't have any more fuel and it'll have nowhere to go.
You can also use suppressant foam, this acts as a barrier to keep unburned fuels from being lit up.
Another way to stop a fire is water. If nothing else works then the only thing we can do is wait for rain and hope that it happens soon.
