Probable Effects of Solar Diameter Variations on Earth System Processes

Uzmah Bilkees ^[2] | Rajeev Kumar Singh ^[3]

Abstract: Earth system processes (ESP) are an interconnected group of processes in which continuous changes are characterized through which material or energy flows. There is a remarkable difference between ESP on blue planet and other planetary neighbours as it shows cycling of matter comprehensively. The exclusive thermodynamic state of the blue planet i. e. , Earth is a kind of special case thermodynamic equilibrium (TE) sustained with the help of these cyclic activities. In this study, we want to emphasize what are the probable effects of the solar diameter variations on the ESP. The Earth as known to us is a system in a steady state with non-equilibrium. Energy balance in it is maintained by the solar radiation absorption and terrestrial radiation emission back into space. While looking at the equations and the data about the processes of variation of solar diameter, we can infer that the amount of irradiance on the surface of the Earth will also be affected. As it clear that the free energy degrading processes subsequently lower temperatures on the Earth. So we presume that the Earth system processes too will have an impact due to solar mass erosion and diameter variation.
