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.
Natural light sources include the sun, moon, stars, fire, and bioluminescent organisms.
Sources of heat include the sun, fire, and electrical heaters. Sources of light include the sun, light bulbs, and candles.
The most difficult part of the fire triangle to eliminate is the heat source, as it can be challenging to completely remove all potential sources of heat that could ignite a fire. Heat can be generated from various sources such as electrical equipment, open flames, or friction, making it difficult to control and prevent in all situations.
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 earth interior
The sun, the moon, and stars are three natural light sources.
Fire, Sun, and lights.
It is a natural source of heat energy
fire
Sunlight, fire, and pee
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.
Natural energy sources
fire for heat,light and sun for light.
