• Expansion of a red giant

• Existence of a black hole

• Formation of a protostar

What is the final stage in the life cycle of a star?

• Puppy

• Rainbow

• Supernova, white dwarf, or black hole

• Unicorn

How does the formation of the Sun differ from the formation of other stars?

• Color and brightness

• Composition and size

• Distance from Earth

• Age and lifespan

What evidence supports the Big Bang Theory?

• Fossil records, continental drift, and volcanic activity

• Solar flares, lunar phases, and asteroid impacts

• Tectonic plate movement, ocean currents, and seismic activity

• Cosmic microwave background radiation, redshift of galaxies, and abundance of light elements

What are the main elements formed during the life cycle of a star?

How does the mass of a star affect its life cycle?

• It causes the star to move closer to Earth

• It determines its color and size

• It has no effect on its life cycle

• It determines its temperature, luminosity, and how it will eventually die.
