SOLAR SYSTEM

Detailed explanation-1: -A granule is a convection cell in the Sun’s photosphere. They are caused by convection currents of plasma in the Sun’s convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.

Detailed explanation-2: -Granulation tissue formation is part of a normal healing process. Under certain conditions, such as infection, self-mutilation, or a local reaction to a chronically implanted, foreign material, this tissue grows uncontrollably and becomes very vascular and secretive.

Detailed explanation-3: -The hot gas then cools at the top of the column and sinks down in the darker regions surrounding each granule. Thus, granulation just represents the tops of convection currents that are transferring heat from below the solar surface to the surface.

Detailed explanation-4: -In quiet regions on the solar surface, turbulent convective motions of granulation play an important role in creating small-scale magnetic structures, as well as in energy injection into the upper atmosphere.

Detailed explanation-5: -They are both convective regions, but they have different shapes and sizes. Granules are characterized by vertical flows. Supergranules, while driven vertically, can be seen primarily as large horizontal motions.
