1. Scientists use models of the Sun to better understand how it works. The currently accepted model of the Sun indicates that it has a dense core
surrounded by different layers. How is energy transferred from the core of
the Sun to its outer layers?
A. Energy radiates outward from the core as visible light.
B. Energy is carried inward from the outer layers by convection.
C. Energy is radiated out from the core first, then carried to the outer layers
by convection.
D. Energy is carried out from the core by convection first, then radiated to
the outer layers.
