The structural layers of the sun are shown in the cross-sectional diagram. An image of six concentric circles is shown. The six layers thus formed are of varying thickness. The layers in order from inside out are labeled, A, B, C, D, E, F.

Which layer represents the radiative zone? (5 points)

a
A

b
B

c
C

d
D

D

Explanation:

I just finished the test

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
