question 1 of 10 the farther a star is away from earth, the more it is a. red shifted b. expanding c. blue shifted d. shrinking

Answer

Brief Explanations:

According to the Doppler - effect in astronomy, as a star moves away from Earth (receding), its light is shifted towards the red - end of the spectrum (red - shifted). The farther the star is from Earth, the greater the red - shift due to the expansion of the universe. Blue - shift occurs when an object is moving towards Earth. Stars are not generally expanding or shrinking in relation to their distance from Earth in the context of this question.

Answer:

A. red shifted
