The three correct answers related to the relationship between nebulae and stars are:
-
Nebulae form from stars - When a star exhausts its nuclear fuel, it can explode (as a supernova) or shed its outer layers, creating a nebula.
-
Stars form from nebulae - Nebulae are regions of gas and dust where new stars can form through the process of gravitational collapse.
-
Nebulae explode to form stars - More accurately, when the matter in a nebula collapses under gravity, it can lead to the formation of new stars.
The other statements are incorrect or misleading:
- "Stars explored to farm nebulas" is not a recognized relationship.
- "Nebula's found inside stars" is incorrect; nebulae are separate structures.
- "Stars are pulled towards nebula" is not a correct depiction of the relationship.
So, the valid points focus on the cyclical nature of star and nebula formation and destruction.
