O A. 11 year solar sunspot cycles change the amount of radiation given off by the Sun.
O B. As the Sun rotates more energy is scattered to space and less is retained on the surface.
O C. Cycles of solar flares and prominences heat and cool the layers below the Sun's surface.
O D. Solar energy is affected by the core output of photons.
How does energy makes its way from the nuclear core of the Sun to its atmosphere?
Choose the correct order for each layer.

Matching These are wrong. Please fix. Thank you.arrow_forward62. Pressure of the Photosphere. The gas pressure of the photosphere changes substantially from its upper levels to its lower levels. Near the top of the photosphere, the temperature is about 4500 K and there are about 1.6 x 1016 gas particles per cubic centimeter. In the middle, the temperature is about 5800 K and there are about 1.0 x 10" gas particles per cubic centimeter. At the bottom of the photosphere, the temperature is about 7000 K and there are about 1.5 × 10" gas particles per cubic centimeter.
