Test your basic knowledge |

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Population 1 with higher metals and contain many young stars in star clusters. Distribution of stars is everywhere in disk (arms only have 5% more stars)






2. Collections of young - hot stars






3. 30AU to 50Au from sun - consists of ancietn premordial objects made of frozen ice and dust-35000 objects or more that are larger than 100 km in diameter and many more smaller than this






4. An object that may remain after a star explodes






5. Dark - reddish - low-pressure bands in Jupiter's atmosphere






6. When material is heated and moves taking the heat energy with it






7. Wave- only waves cause an interference pattern when passing through a double slit - particle- only particles deposit energy at specific locations (the way an image builds up on digital camera)






8. The law that describes the blackbody curve - and let to quantum mechanics.

9. A telescope that uses lenses to focus light






10. A very low mass particle formed in solar fusion reactions that reacts only weakly with matter






11. VENUS






12. A logarithmically scaled value for the measured brightness of a star.






13. Mercury






14. A fusion process in which protons build together to form helium






15. Stars orvits do not define the spiral patterns - instead they are density waves that move at slower speeds (arms are defined by young O and B stars and gas clouds)






16. A measure of the force of gravity on an object






17. Electromagnetic Radiation






18. Moon in less than the angular diameter of the Sun.






19. Clouds of low density gas often found glowing faintly on either side of an AGN.






20. First accurately measured the speed of light in a vacuum






21. The rock that makes up the lunar maria






22. Light scattered through the atmosphere that degrades astronomical images






23. A star that is burning hydrogen to helium in a shell surrounding it's core






24. A continuous spectrum of light missing energy at a few wave lengths.






25. The amount of density needed to stop the universe from expanding and to begin the big crunch represented by Pc






26. Distribution of dust (tells us disk is thin) - find distances to O&B stars and H2 regions (arms are sights of star formation and OB stars live and die at location of birth) -Milky way has four arms. Sun is in spur apart from arms.






27. The name for the only seriously considered theory of the universe.






28. The apparent backward motion of a planet against the background of stars.






29. A quantity measuring the stability of the Earth's atmosphere






30. The gap inthe outer portion of Saturn's A ring






31. The point in its orbit where a planet is nearest the sun






32. Heavier elements such as iron - silicon - magnesium - sulfer - nickel






33. The gap inthe outer portion of Saturn's A ring






34. Jupiter - Saturn - Uranus - Neptune






35. Jupiter - Saturn - Uranus - Neptune






36. Population 1- similar to the sun and 2% of elements are metal - Population 2- formed before gas was metal- only a fraction of mass is metal.






37. Radiation (possibly left over from the big bang) that fills the universe. Perfect black body spectrum and tells us a bit aout how galaxies are formed.






38. A term referring to the orbital character of stars near the Sun






39. Norhern lowlands- darker in color and have far fewer craters as if an ancient sea or ice field covered them. southern highlands- much higher in density of craters.






40. The dark - relativley smooth areas on the moon; Latin for sea






41. 1-orbit aroudn the sun 2- are in hydrostatic equilibrium and 'mostly round' 3- have not cleared debris around its orbit 4- are not satellites






42. Hurricane-like vortex in southern-hemisphere winds to north and south blow in opposite directions which keep it spinning and with no subsurface features like mountians it persists.






43. A galaxy sending out a stream of material from its nucleus






44. Either Io -Europa - Ganymede - or Callisto






45. The oldest part of the Milky Way






46. The apparent path of the Sun through the stars on the celestial sphere.






47. The gap etween saturn's A and B rings






48. Largest moon in solar system - two differenet types of terrain - darker terrain is older - NOT ACTIVE SURFACE






49. The force of attraction between any two objects having mass






50. In what chemical form are jupiters nitrogen - carbon and oxygen?
