- A.It indicates the star's distance from Earth.
- B.It shows the star's temperature and luminosity relationship.
- C.It reveals the star's chemical composition.
- D.It determines the star's age.
Model answer
What a good answer should say
- It shows the star's temperature and luminosity relationship.
Explanation
Why this works
The evidence from the Hertzsprung-Russell diagram illustrates how stars are classified based on their temperature and luminosity. This implies that the diagram provides a visual representation of stellar evolution and characteristics.
Therefore, we conclude that the HR diagram is a vital tool for understanding stellar properties.
