PRACTICE QUESTIONS FOR STARS AND PLANETARY REVISION QUESTIONS:
Life cycle of an average sized star
1.
2.
3.
4.
5.
6.
Draw a diagram to describe the life cycle of an average sized star like our sun.
Describe how the fuel use changes (from using hydrogen) throughout the different stages
Explain how the mass of the star is related to the death of the star
Explain how changes in gravity start the life cycle of a star
Explain how changes in gravity lead to the formation of a red giant
Describe the energy changes that occur from when a star is born, until when it has died.
Life cycle of large and massive stars
1. Describe the difference in the stages of the life cycle for a large and massive star compared
to an average star
2. Describe the fuel use changes from birth to death for a black hole
3. Describe the fuel use changes from birth to death for a neutron star
4. Explain how the energy changes are involved in each of their life cycles from birth to death.
5. Explain how the gravity changes are related to the final stages in the life cycle of large and
massive stars.
HR diagram interpretation
1. Explain the position of white dwarfs on the HR diagram in relation to fuel use, size, mass,
luminosity and temperature (and surface area)
2. Do the same for the position of red giants
Planetary statistics
1. Make up a chart showing a comparision in the size, composition, atmospheric composition,
temperature, position, n.o of moons of the planets in relation to the sun.
2. Explain how the planets are thought to have formed. Draw a flow chart and annotate
explanations of the difference in size and composition in particular, in relation to
temperature.
Moons
1. Discuss, with reasons, the formation of the moons of Earth and Mars. Include the origin of
moons, difference in the planetary orbits of Earth and Mars and gravitational pull.
