Responses

The highest temperatures are from the corona.
The highest temperatures are from the corona.

The highest temperatures are from the radiative zone.
The highest temperatures are from the radiative zone.

The lowest temperatures are from the core.

Answer 1

The scientists can use temperature measurements to identify the sun's layers by noting that the highest temperatures are found in the corona. This outermost layer can reach temperatures of millions of degrees Celsius, especially during solar flares and coronal mass ejections. In contrast, the photosphere, which is the visible surface of the sun, has much lower temperatures, around 5,500 degrees Celsius. Thus, if they observe very high temperature readings, they can conclude they are observing the corona, while lower temperatures would indicate that they are observing the photosphere.
