Answer to Question 1

Astronomers have mapped a magnetic carpet of looped magnetic fields extending up through the photosphere. Because the gas in the chromosphere and the corona has very low densities, it can't resist movements of the magnetic fields. Turbulence below the photosphere seems to flick the magnetic loops back and forth and whip the gas about, heating the gas. Further observations have revealed magnetic waves generated by turbulence below the photosphere traveling up into the chromosphere and corona and heating the gas.
