The center of the sun, the ___, produces the energy that eventually reaches us and warms the Earth.
core
radiative zone
corona
convective zone
Solar flares, prominences, coronal holes, and coronal mass ejections are all due to disturbances in _____ on the sun.
the convective zone
the radiative zone
the core
magnetic fields
These appear darker than the rest of the sun's surface (photosphere) because the strong magnetic fields associated with them decrease convection from below the surface, cooling this area.
