Arrange the inner layers of the Sun in order starting with the innermost layer. Energy produced by nuclear reactions in
the core
travels to this zone through radiation
The center of the Sun where all the Sun's
energy
is produced
In this zone, hotter gases from the base
travel to
the top and cooler gases sink to the
bottom due
to the temperature difference
This zone is visible from Earth.
