How does wildfire spread?
|
Some habitats thrive because of fire. Grasslands, for example, develop in dry areas where fires are frequent. The grass regenerates quickly and the animal life has adapted to such conditions. But fires can burn out of control. In a forest, it can spread through leaf litter and undergrowth, or through the crowns of trees. Sometimes firestorms develop, in which vicious winds are whipped up by the convection currents produced by the heat, pulling animals and fire-fighters into the heart of the blaze. | | Forest fires are sprayed from the air with water and chemicals, and bulldozers make fire breaks through the trees. |
