Question

Quizplus · Accepted Answer

Solar energy reaches the Sun's photosphere from the layer just underneath it through convection. Convection is the movement of material due to differences in temperature and density. The hot, less dense material rises while the cooler, denser material sinks, creating a cycle of circulation. In the Sun's outer layers, energy is transported primarily by convection, which brings the energy from the hot interior to the cooler photosphere.
