Question

use the diagram to answer the question.

diagram of stellar evolution

based on the diagram, which statements about stellar evolution are true? select the two correct answers.
(1 point)

• massive stars evolve more slowly than average stars.
• average stars evolve more slowly than massive stars.
• massive stars evolve more quickly than average stars.
• average stars evolve more quickly than massive stars.
• massive and average stars evolve at about the same speed.

Explanation:

Stellar evolution principles show that more massive stars burn through their nuclear fuel at a much faster rate than average (solar-mass) stars, causing them to evolve more quickly. This means average stars evolve more slowly in comparison, and massive stars evolve more quickly than average stars.

Answer:

B. Average stars evolve more slowly than massive stars.
C. Massive stars evolve more quickly than average stars.
