What are the two stages that all stars have in common throughout their life cycle?

• protostar

• supergiant

• white dwarf

• nebula

Which term describes a cloud of gas and dust where stars are born?

• Supernova

• Nebula

• White Dwarf

• Black Hole

What is the final stage of a low-mass star's life cycle?

• Black Hole

• Neutron Star

• White Dwarf

• Main Sequence

Which event marks the explosive death of a massive star?

• Nebula

• Main Sequence

• Supernova

• Red Giant

What is formed when a massive star collapses after a supernova?

• White Dwarf

• Black Hole or Neutron Star

• Main Sequence Star

• Red Giant

Which stage comes immediately after the main sequence for a star like the Sun?

• Red Giant

• Supernova

• Black Hole

• Nebula

Describe the difference between the life cycle of a low-mass star and a high-mass star.

• Both end as black holes

• Low-mass stars become white dwarfs, high-mass stars may become neutron stars or black holes

• Both become supernovae

• Low-mass stars skip the main sequence

Which sequence correctly illustrates the life cycle of a high-mass star?

• Nebula → Main Sequence → Red Giant → White Dwarf

• Nebula → Main Sequence → Red Supergiant → Supernova → Neutron Star/Black Hole

• Nebula → Main Sequence → Red Giant → Planetary Nebula → White Dwarf

• Nebula → Main Sequence → White Dwarf → Black Hole

Explain how a supernova can contribute to the formation of new stars and planets.

• By absorbing all nearby material

• By spreading heavy elements into space, which can form new stars and planets

• By turning into a black hole

• By cooling down and forming a nebula
