Question 2
What happens to energy in the convection zone of the Sun?
A) Energy slowly leaks outward through the diffusion of photons that repeatedly bounce off ions and electrons.
B) Energy is produced in the convection zone by nuclear fusion.
C) Energy is transported outward by the rising of hot plasma and the sinking of cooler plasma.
