Question

Quizplus · Accepted Answer

Granulation is caused by rising and sinking gases below the photosphere. These convection currents cause the appearance of small bright and dark granules on the solar surface. Sunspots, shock waves in the corona, and the solar wind do not directly cause granulation. While heating in the chromosphere may be related to the underlying convection, it is not the cause of granulation itself.
