How do we know what goes on under the surface of the Sun?
A)We have X-ray images from satellites of the interior of the Sun.
B)Astronomers create mathematical models that use the laws of physics,the Sun's observed composition and mass,and computers to predict internal conditions.
C)We have sent probes below the surface of the Sun.
D)By measuring Doppler shifts,we observe vibrations of the Sun's surface that are created deep within the Sun.
E)both B and D

Quizplus · Accepted Answer

We do not have X-ray images or probes that have gone beneath the surface of the Sun. Instead, astronomers create mathematical models that predict internal conditions based on observations of the Sun's composition, mass, and physical laws (choice B), and they also observe vibrations of the Sun's surface that are created deep within the Sun by measuring Doppler shifts (choice D). Therefore, the correct answer is E, which includes both options.
