BCertainly! Here is a 10-question quiz on star formation and star life cycles:
1. What is the primary element that fuels a star during its main sequence phase?
a) Helium
b) Hydrogen
c) Carbon
d) Oxygen
Hydrogen nuclei are converted into helium during nuclear fusion in the core, releasing enough pressure to counteract the force of gravity
D2. What is the force that balances the inward pull of gravity in a star, preventing its collapse?
a) Nuclear fusion
b) Electromagnetic force
c) Gravitational force
d) Radiation pressure
C3. What is the first stage in the life cycle of a star?
a) Red giant
b) Main sequence
c) Nebula
d) Planetary nebula
a4. At what point in a star's life cycle does it run out of nuclear fuel and eventually collapse?
a) Red giant phase
b) Protostar phase
c) White dwarf phase
d) Supernova phase
b5. What type of star is formed from the remnants of a supernova explosion?
a) Black hole
b) Neutron star
c) Red giant
d) White dwarf
B6. What is the end stage of a low to medium-mass star, like our Sun?
a) Red supergiant
b) Planetary nebula
c) Neutron star
d) Black hole
C7. Which process ultimately leads to the formation of a star from a cloud of gas and dust?
a) Nuclear fission
b) Nuclear fusion
c) Gravitational collapse
d) Stellar explosion
B8. What is the term for a star that has exhausted its nuclear fuel and collapsed to a very small size?
a) Red dwarf
b) White dwarf
c) Giant star
d) Pulsar
C9. What is the name of the massive explosion that occurs when a massive star reaches the end of its life cycle?
a) Black hole formation
b) Nova explosion
c) Supernova explosion
d) Red giant phase
A and then c10. How do stars like our Sun eventually die?
a) Expand to form a red supergiant
b) Collapse to form a black hole
c) Shed their outer layers to form a planetary nebula
d) Explode in a supernova
