1 - 500 What kind of stars are in the different parts of a spiral galaxy? Young stars are in the arms Old stars are in the center

2 - 100 What is this graph called? HR diagram

2 - 200 What color is the hottest star on the HR diagram? Blue

2 - 300 What are the 2 criteria the graph is based on? Temperature Luminosity (Brightness)

2 - 400 If you know a star’s temperature you can determine its what? Color

2 - 500 If you know a star’s brightness you can determine its’ what? Energy

3 - 100 A star is born when what begins? Hydrogen fusion

3 - 200 The core of MASSIVE stars get hot enough that they can fuse elements as large as what? Iron

3 - 300 Massive stars become ________ then a supernova occurs and they become _________ or ________ Supergiants, neutron stars or blackholes

3 - 400 Why is a black hole black? Light can’t escape its pull of gravity

3 - 500 What causes a supernova? Star collapse and pushes electrons into the nuclei and they get pushed together too much and spring back (in an explosion)

4 - 100 What is the final stage of a low mass main sequence star? Red dwarf

4 - 200 What is the final stage of a ‘medium’ star? Black dwarf

4 - 300 An average star runs out of hydrogen and becomes a _______ then ______ before going into its final stage of life. Red giant then white dwarf

4 - 400 What is the difference between a white and black dwarf? A black dwarf is a white dwarf that has stopped emitting light

4 - 500 What has to be equal for a star to be in equilibrium? Gas pressure (from fusion) and Gravity

5 - 100 What is the study of the universe called? Cosmology

5 - 200 What is the first and second most abundant elements in the universe? First – Hydrogen Second - Helium

5 - 300 Explain the Big Bang Theory A collection of observations and mathematical equations explaining the formation of the universe Universe was condensed into a single point and began expanding 13.8 mya

5 - 400 Why was Leviticus burned to death? Questioning the church and stating that the universe was limitless

5 - 500 Explain the Doppler effect and the universe. The Doppler effect states that as light comes towards you its frequency increases and as it moves away from you its frequency decreases. The universe gives a red shift because the light is moving away from us – because the galaxy is expanding
