Fire is primarily a source of heat, produced through the combustion of materials, which releases energy in the form of heat and light. While fire can occur naturally, such as in wildfires caused by lightning strikes, it is also commonly generated by human activities, such as cooking or heating. Therefore, while fire itself is a source of heat, it can be both natural and man-made.
Examples of heat sources could be grouped into two (2) based on there origin. They are; 1. Natural Heat Sources. The natural heat sources could be sub-divided into two; a. External Source, e.g Sun. b. Internal Source, e.g Geothermal, i.e. Magma. 2. Man-made Heat Sources. These includes heat generated from; a. Electricity, e.g Electric Cooker and Oven. b. Fire, e.g Coal.
The sun, the moon, and stars are three natural light sources.

Examples of natural sources of heat and light include the Sun, which provides sunlight and warmth essential for life on Earth, and fire, which can occur naturally through wildfires or volcanic activity. Additionally, geothermal energy from the Earth's interior can produce heat, while bioluminescent organisms, such as certain types of jellyfish and fireflies, emit light through natural chemical processes. These sources play crucial roles in ecosystems and influence climate and weather patterns.
The three natural sources of heat and light are the sun, fire, and lightning. These sources provide heat and light through processes such as nuclear fusion, combustion, and electrical discharge.

Two categories of heat sources are natural heat sources and artificial heat sources. Natural heat sources include the sun, geothermal energy, and volcanic activity. Artificial heat sources include electric heaters, gas heaters, and oil heaters.
The two major sources of radiant heat in a fire are the flames and the hot surfaces of burning materials.

Two sources of heat are the sun and fire. The sun emits heat and light energy through nuclear fusion in its core, while fire produces heat through the rapid chemical reaction of burning materials.
