how have astronomers formed their ideas about the layers of the sun? (1 point) developing mathematical models based only on known data using theoretical models combined with known data making direct observations of the suns layers observing all the layers during total solar eclipses

Answer

Answer:

B. using theoretical models combined with known data

Brief Explanations:

Direct observation of the sun's layers is not possible due to its extreme nature. Astronomers use theoretical models (like stellar structure equations) along with data from spectroscopy, helioseismology etc. to understand the sun's layers. During a total solar eclipse, only the outer - most visible layer (the corona) is easily observable, not all layers. And relying only on known data for mathematical models is too limiting as some aspects require theoretical assumptions and extrapolations.
