Question

The life trajectory of a stellar nebula is shown. The stellar nebula, a purple gas ball turns into an average star, depicted as a yellow circle, within 500 million years. The average star turns into a red giant, depicted as a medium sized red circle, within 10000 million years. The red giant turns into a planetary nebula, a bright star surrounded by green and blue gases, within 1000 million years. And the planetary nebula gradually cools into a white dwarf, depicted as a small white circle. The stellar nebula can also turn into a massive star, depicted as a medium blue circle, within 0.1 million years. The massive star turns into a red supergiant, depicted as a large orange circle, within 15 million years. The red supergiant turns into a supernova, a bright white star, within 1 million years. The supernova can either turn into a neutron star, depicted as a yellow sphere with white rays coming out of its sides, or a black hole, a small black circle surrounded by purple rays.

Based on the diagram, which statements about stellar evolution are true? Select the two correct answers.

Massive stars evolve more quickly than average stars.

Answer 1

Based on the information provided about the life trajectory of stellar nebulae and the evolution of average stars and massive stars, the two correct statements are:

1. Average stars evolve more slowly than massive stars. - This is true as the average star takes much longer to evolve through its stages compared to the massive star, which evolves rapidly.

2. Massive stars evolve more quickly than average stars. - This is also true as the diagram indicates that massive stars undergo their evolution stages in significantly shorter timeframes than average stars.

The other statements regarding average stars evolving more quickly, and massive stars evolving more slowly than average stars, are incorrect based on the provided information.
