sun fuel electricity and friction
The four main sources of heat are the sun, geothermal energy from the Earth's core, friction from mechanical processes, and chemical reactions such as combustion.
Two common heat sources for evaporation are the sun and industrial heating elements. The sun provides natural heat to evaporate water outdoors, while industrial heating elements like electric heaters or steam are used in controlled environments for processes like distillation or drying.
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.
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.
The main sources of heat are the sun, which provides solar radiation, and the Earth's core, which generates geothermal heat. Other sources of heat include human activities such as burning fossil fuels and electrical appliances.

Sun is the source of heat. It also provides thermal energy.
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.
Heat from the sun evaporates water from the oceans which then falls as rain
