What 2 part of the sun outer layer visible from earth during a solar eclipse?

During a solar eclipse, the two parts of the Sun's outer layer that are visible from Earth are the chromosphere and the corona. The chromosphere appears as a thin red ring just beyond the Sun's disk, while the corona is the outermost layer, forming a halo of plasma that extends far into space. These layers become visible when the moon obscures the bright light of the Sun's surface.
