Question

place the stages of our suns formation in order: beginning (birth) 1 nebula 2 planetary nebula 3 red giant 4 proto - star 5 white dwarf star 6 main sequence star end (death)

Explanation:

Stars form from nebulae. A nebula collapses to form a proto - star. The proto - star evolves into a main sequence star. After the main sequence stage, for a star like the Sun, it becomes a red giant. Then it ejects its outer layers to form a planetary nebula and leaves behind a white dwarf as its final stage.

Answer:

1. Nebula
2. Proto - star
3. Main Sequence Star
4. Red Giant
5. Planetary nebula
6. White Dwarf Star
