Astronomers have formed their ideas about the layers of the sun primarily by using theoretical models combined with known data. This approach allows them to integrate observations, such as those from solar radiation and solar oscillations, with theoretical physics to gain insights into the sun's structure and behavior. While observations during total solar eclipses and direct observations contribute to our understanding, the comprehensive models developed over time are central to explaining the sun's layers.

Two astronomers are viewing temperature data from each of the sun's layers, but the layers aren't identified. Describe one way the scientists can use temperature to identify which layer they are studying.(1 point) Responses The highest temperatures are from the radiative zone. The highest temperatures are from the radiative zone. The lowest temperatures are from the core. The lowest temperatures are from the core. The lowest temperatures are from the photosphere. The lowest temperatures are from the photosphere. The highest temperatures are from the corona.
One way the scientists can use temperature to identify which layer they are studying is by noting that the highest temperatures are from the corona. The corona, which is the outermost layer of the sun's atmosphere, has temperatures that can exceed a million degrees Celsius, significantly higher than those of the inner layers. In contrast, the core has the highest temperatures, followed by the radiative zone and then the convective zone, with the photosphere being the coolest layer. Therefore, identifying the maximum temperature as characteristic of the corona can help them determine which layer they are observing.
Which is the origin of the sun’s energy?(1 point) Responses charged particles charged particles burning hydrogen burning hydrogen solar flares solar flares nuclear fusion nuclear fusion
The origin of the sun’s energy is nuclear fusion. In the core of the sun, hydrogen nuclei fuse together under extreme pressure and temperature to form helium, releasing a tremendous amount of energy in the process. This energy is what powers the sun and provides light and heat to the solar system.
