What causes natural forest fires?

Answer 1

1) Forest fires can occur due to lightening which burns the trees but rain after it extinguishes fire causing less damage to the trees.

2) Fire needs oxygen, fuel and heat to start. Oxygen is present all around in the air, wood of the trees act as fuel and heat does not allow the fire to extinguish. At a temperature of 572 degree wood releases a gas that reacts with oxygen present in air and triggers a flame which will give heat to the surrounding woods and the fire will start growing more and more strong. This can also happen in the cold days.

3) Earthquake is also responsible for the forest fires. In 1906 earthquake in San Francisco causes fire. Other reason for fire is volcanoes and drought.

4) High temperature and low humidity (dryness) provides favorable conditions to the fire and hence it can start

Answer 2

Natural causes of wildfires and bushfires include:

• lightning strikes
• dryness of the vegetation caused by intense prolonged heat, as in heatwave conditions
• strong, gusting winds which fan the flames

Answer 3

The main cause of natural forest fire is 'During the hot clime the leaves and wood of the forest trees become dry and when they come in contact among themselves continuously, heat generates and sparks of fire run from one jungle to other with the help of wind and causes havoc. The recent natural forest fire in Australia is still fresh in our memory for its vastness and losses sustained therein.

Answer 4

Natural forest fires can be caused by lightning strikes, volcanic activity, or spontaneous combustion from sources such as decaying vegetation. Dry and hot weather conditions can also contribute to the spread and intensity of natural fires in forests.
