The transfer of heat from the sun to the earth is a complex interplay of radiation, absorption, reflection, and re-emission. Understanding these mechanisms is crucial for comprehending the Earth’s climate system, weather patterns, and the delicate balance that sustains life.
Solar energy, however, can travel from the sun to the Earth without the need for a physical substance to transmit the energy. This feature of electromagnetic energy makes it possible for the Earth to receive solar energy, including heat. Some of the solar energy that arrives at the Earth bounces off the atmosphere and clouds and back into space.
The heat of the Sun is transferred to us by radiation because there is a space (vacuum) between the sun and the Earth and the transfer of heat by radiation doesn’t need any material medium through which heat transfers.
The heat of the Sun is transferred to the Earth without any need for a material medium and this way is known as the transfer of heat by radiation, heat is transferred by radiation through material media & non-material ones, The heat is transferred from the heater to our bodies by convection & radiation.
Most of the Sun’s energy reaching Earth includes visible light and infrared radiation but some is in the form of plasma and solar wind particles. Other forms of radiation from the Sun can reach Earth as part of the solar wind, but in smaller quantities and with longer travel times.
Solar radiation is created by nuclear fusion reactions in the sun's core, which causes it to emit a large amount of electromagnetic radiation, mostly in the form of visible light. This radiation is the energy that heats the Earth. The sun's surface emits about 63 million watts of energy per square meter.
