prominence | a loop of relativity cool, incandescent gas that extends above the photosphere and above the suns edge as seen from earth. |
core | the central part of earth below mantle. |
radiative zone | is the layer of the sun through energy is transferred away from the core by radiation . |
convection zone | is the layer of the sun through which energy travels by convection from the radiative zone to the photosphere. |
