Answer: Sun’s atmosphere
Notes: The chromosphere, located in the solar atmosphere and is a layer characterized by intense solar activity. It has a vital function in transferring non-thermal energy, which effectively heats the corona and fuels the solar wind, extending beyond the boundaries of the solar atmosphere. According to a recent study, the bright grains detected in the chromosphere of the Sun are a result of shocks moving upwards in the solar plasma. These grains exhibit higher temperature increases than previously estimated.
