Almost every year, Australia experiences a ‘bushfire season.’ A bushfire is a fire that occurs in a large area of bush or forest and spreads very fast. Bushfires are started either by careless human activity or by natural causes. When the ground and vegetation are very dry, like they are in a drought, the fires spread quickly.
The major cause of bushfire in Australia is dry lightning. Dry lightning happens when it rains, but most or all of the rain evaporates before reaching the ground because of intense heat. Australia has had a long period of drought and high temperatures. This has led to a lot of vegetation drying up. When dry lightning occurs, it strikes the dry leaves and trees and starts a fire. Some irresponsible people have also started the fire.
