Final answer:
Fire spreads through conduction, convection, and radiation. Conduction is NOT a method by which fire spreads.
Step-by-step explanation:
Fire spreads through a combination of conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between objects. For example, if a wooden stick touches a flame, the heat from the flame is conducted to the stick, causing it to catch on fire.
Convection is the transfer of heat through the movement of fluids or gases. In the case of a fire, hot air rises and carries heat energy away from the fire, contributing to its spread.
Radiation is the transfer of heat through electromagnetic waves. In the case of a fire, infrared radiation is emitted, which can transfer heat to nearby objects without the need for direct contact. The radiation from a fire can be felt as warmth by people standing near it, even if they are not directly in the line of sight of the flames.
Therefore, conduction is NOT a method by which fire spreads.
