9. Waves $400 In the diagram below, which type of wave has the most energy? • Radio • Gamma • Infrared • Ultraviolet

10. Waves $500 Which electromagnetic wave has the longest wavelength and is used to explore the universe? • Gamma • Radio • Infrared • Visible Light

11. The Sun $100 Why does the sun appear larger than other stars? • Distance to Earth • Yellow color • Chemical composition • High temperature

12. The Sun $200 Which group, on the HR Diagram, does our Sun belong to? • White Dwarfs • Giants • Super Giants • Main Sequence

13. The Sun $300 It takes approximately 8 minutes and 20 seconds for light produced by the Sun to reach the Earth. Therefore, the Sun is located _ • Much less than one light year from the Earth • About 8.3 light years from the Earth • More than 160 light years from the Earth • About one light year from the Earth

14. The Sun $400 Which statement best describes Earth’s sun? • The sun is an average star in terms of size and temperature • The sun is the glowing remains of an older, dying star • The sun is a collection of stars held together by gravity • The sun is a red giant that will soon become a black dwarf star

15. The Sun $500 Energy is transferred from the Sun to Earth mainly by ___ • Molecular collisions • Density currents • Red shifts • Electromagnetic waves

16. Distances $100 If a star’s light takes 600 years to reach the Earth, we know the star is ___ • Showing a red shift • Moving away from us • Moving toward us • 600 light years away

17. Distances $200 Which unit would you use to best measure distances in the solar system? • Meter • Light year • Astronomical unit • Kilometer

18. Distances $300 Rigel is 490 light years from Earth. If Rigel explodes today (goes supernova) when will scientists on Earth be able to detect this stellar explosion? • Between 4-6 am • 490 years from now • 1000 years from now • When the sun is low on the horizon

19. Distances $400 The distance between objects in the universe are usually measured in light years because • Many objects in the universe are in close proximity to Earth • Only electromagnetic waves, such as light, can travel through a vacuum • Smaller units, such as kilometers, result in values that are impractical and large • Many objects in the universe radiate light that can be seen from Earth

20. Distances $500 A light year is an appropriate unit for measuring the ____. • Distance between galaxies • Time it takes to travel to Mars • Time it takes to travel to the Sun • Distance between the Earth and the Moon

21. HR Diagram $100 Which color of stars has the highest surface temperature? • Red • Blue • White • Yellow

22. HR Diagram $200 What is the primary factor that determines which path a star will take on the lifecycle diagram? • Nuclear fusion • Gravity • Mass • Chemical composition

23. HR Diagram $300 What is the general relationship between the surface temperature and brightness of a Main Sequence star? • As the temperature increases, the brightness increases • As the temperature increases, the brightness decreases • As the temperature increases, the brightness remains the same • As the temperature remains the same, the brightness increases

24. HR Diagram $400 A star that is extremely bright, but has a low temperature probably belongs to which group on the H-R Diagram? • Main sequence • White dwarfs • Giants • Super giants

25. HR Diagram $500 A star that is low in magnitude, but has a high surface temperature probably belongs to which group on the H-R Diagram? • White dwarfs • Giants • Super giants • Main sequence

26. Components of the Universe $100 Which of these best describes the composition of a nebula such as the Crab Nebula? • Clouds of dust and gas • Ice crystals • Planets and moons • Large asteroids

27. Components of the Universe $200 Spiral and irregular galaxies contain a lot of gas and dust. How is this related to the age of the stars in the galaxy? • A collection of gas and dust is needed to form new stars • All dust in galaxies is left over from old stars that died a long time ago • Gas and dust are a product of nuclear fusion in middle aged stars • There is no connection between gas and dust and the age of stars in a galaxy

28. Components of the Universe $300 What do all galaxies have in common? • They are the same shape • They are made of stars • They are the same distance from Earth • They travel around the Sun

29. Components of the Universe $400 In what way is the life cycle of stars a cycle? • The number of stars in the universe is constant • All types of stars follow a predictable pattern of change • Black holes cause the compression of matter, which in time, forms new stars • Supernovas give off dust and gas, which eventually form nebulae

30. Components of the Universe $500 Which of the following best explains why stars are different colors? • The star are in different galaxies • The stars are different distances away • The stars are at different stages in their life cycles • The stars have different numbers of planets orbiting them

31. Origins of the Universe $100 What information can astronomers obtain from spectrographs about stars? • Temperature and chemical composition • Size and distance • Temperature and distance • Chemical composition and distance
