What is the life cycle of a star?
Keywords:
  • Fusion: Nuclear fusion involves two atomic nuclei joining to make a large nucleus. Energy is released when this happens. (2)
  • Equilibrium: when there is a balance of opposing forces or influences. (1)
  • Universe: All of space and time, energy and matter. (1)
  • Supernova: A supernova is the explosion of a star -- the largest explosion that takes place in space. (1)
  • Gravity: Gravity is the attraction by which a planet or other body draws objects toward its center. (1)
  • Life cycle: The different stages of the development of a star. (1)
  • Nebula: A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases. (1)
  • Nuclei: The centre of an atom made of protons and neutrons. (1)

(Physics only) Students should be able to explain how fusion processes lead to the formation of new elements. (Physics only) How are new elements formed?
(Physics only) A star goes through a life cycle. The life cycle is determined by the size of the star. (Physics only) What is a star's life cycle determined by?
(Physics only) The Sun was formed from a cloud of dust and gas (nebula) pulled together by gravitational attraction. (Physics only) What was the sun formed from and how?

(Physics only) Students should be able to explain how, at the start of a star's life cycle, the dust and gas drawn together by gravity causes fusion reactions (Physics only) How do the fusion reactions in a star begin?

(Physics only) Students should be able to explain that fusion reactions lead to an equilibrium between the gravitational collapse of a star and the expansion of a star due to fusion energy. (Physics only) What do these fusion reactions lead to?

EW Explain the forces involved in the formation of stars and the equilibrium reached in their main stage.
(Physics only) Fusion processes in stars produce all of the naturally occurring elements. (Physics only) How are all the naturally occurring elements formed?

(Physics only) Elements heavier than iron are produced in a supernova. (Physics only) Which elements are produced in a supernova?
(Physics only) The explosion of a massive star (supernova) distributes the elements throughout the universe. (Physics only) How are elements distributed around the universe?
