Life Cycle of Star

Multiple Choice

What is a Nebula?

• An enormous cloud of gas and dust

• A type of planet

• A cloud of helium

• a ball of heat and energy

Multiple Choice

How is the life cycle of a star determined?

• by fusion

• by its mass

• by the color

• by the tempature

Multiple Choice

What is protostar

• a diagram of a star

• a ball of heat, a baby 'star'

• Whats left over from the fusion

• a ball that emits no light or heat, basically a ball of carbon

Multiple Choice

what is the main sequence

• the main part of a stars lifecycle

• The end of a stars lifecycle

• The first part of a stars lifecycle

Multiple Choice

What happens during the red giant phase

• The surface of the star expands away from the core

• The surface of the star moves towards the core

• The star explodes

Match

Match the description to the stages of a low mass star

• A large interstellar cloud of gas and dust in space that is composed mostly of hydrogen and helium

• A very young star that is still in the process of formation. Nuclear Fusion has not began.

  
  

• Nuclear Fusion has occurred and the newly formed star is in this phase of its life cycle. 

  
  

• When hydrogen fusion can no longer take place inside the core of a medium to low mass star and the increased internal gravity collapse, the star is in this phase of it lifecycle.

• In the end, the Star’s gravity can no longer contain the outer layers of the Red Giant and the star ejects these layers into space in the form of an ionized gas that glows bright. his glowing gas and debris are called a his glowing gas and debris are called a ?

Multiple Select

a smaller red super giant ends up as (choose 2)

• a black hole

• a neutron star

• a white dwarf

• a black dwarf

• a planetary nebula

Multiple Choice

What is neutron star

• The core left over from the super nova for high mass stars

• The core left over from the super nova for low mass stars

• The ending of a super massive star; the gravity of the core is so strong the core collapses on itself creating a gravitational pull so strong nothing including light can escape it

Match

Match the following stages with the corresponding star types after the main sequence.

• supergiant

• protostar

• white dwarf

• red giant

High mass star

Early stage star

End stage of a low mass star

Late stage of a low mass star

• High mass star

• Early stage star

• End stage of a low mass star

• Late stage of a low mass star
