For tiny farmers, controlled fires can be a handy method to apparent overgrown spots and launch nutrients from standing vegetation back again in to the soil.[29] Nonetheless, this helpful technique is additionally problematic.
Convection is the process of heat transfer by fluids (gases and liquids). Within a fire, incredibly hot gases rise and cooler air descends, creating a cycle that could rapidly spread flames upwards and in the course of a developing, Primarily affecting better floors and enclosed spaces.
