Fire behavior includes such things as how fast a fire burns (rate of spread), how hot it burns (fire intensity), the presence of fire whirls, and ember production and spotting.

What burns fire faster?

The more oxygen molecules that collide per second with the fuel, the faster the combustion reaction is. You can increase the surface area of a solid by breaking it up into smaller pieces. If you chop or break up wood into small pieces, it will ignite and burn more quickly than larger pieces of wood.

Fires can sustain themselves by the further release of heat energy in the process of combustion and may propagate, provided there is a continuous supply of oxygen and fuel. Fires may become uncontrolled and cause great damage to and destruction of human life, animals, plants and property.

How did humans make fire?

If early humans controlled it, how did they start a fire? We do not have firm answers, but they may have used pieces of flint stones banged together to created sparks.
