The center of the sun, the ___, produces the energy that eventually reaches us and warms the Earth.
core
radiative zone
corona
convective zone
The outer atmosphere of the sun, only visible during a total solar eclipse, is called the ___.
penumbra
umbra
corona
corolla
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
