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. What Ole Roemer used to measure the speed of light in a vacuum






2. Sulfurous volcanoes - pools of liquid sulfur - surface resembles cheese pizza ACTIVE SURFACE






3. Distance from sun to nucleus- 8 kiloparsecs (26000 LY) - diameter of Milky way- 150000 LY - length for sun to orbit once around milky way- 250 million years






4. The rate of expansion of the universe.






5. Why does the earth have few craters while the moon has many?






6. Small bulges - loosely wound - massive arms - arms have many H2 regions and look very lumpy






7. The location around an atom where an electron resides.






8. The oldest terrain on the moon






9. The line on an H-are diagram going from upper left to lower right where normal stars of different masses reside.






10. 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)






11. The process that powers the sun and hydrogen bombs






12. A massive variable star used to find distances to the galaxies or clusters that contain them.






13. The universe is isotropic - homogeneous - and without beginning or end in time and space. If the universe is truly homogeneous then every line of sight will eventually end on a galaxy. If it has existed forever then there has been enough time for lig

14. What Ole Roemer used to measure the speed of light in a vacuum






15. The line on an H-are diagram going from upper left to lower right where normal stars of different masses reside.






16. A huge sphere of tenuous gas surrounding the nucleus of a comet






17. A measure of how an object resists accelerating when acted upon by a force. It is proportional the amount of matter in an object






18. A highly variable galaxy nucleus of which BL Lac is one. Their light is highly energetic and their spectra are featureless. (face on)






19. Very center of galaxy. suggestion of a black hole






20. Centered on the Earth






21. Formed rapidly - collapsed slower into disk shape - star birth rate is low but lasts longer and ongoing - contain higher mass blue stars.






22. An object that may remain after a star explodes






23. A faint - remarkably uniform distribution of radiation in space






24. When particles are compressed to an unnatural state where their pressure is not related to their temperature






25. The relation that tells how light dims with distance.






26. The normal eastward movement of a planet against the background of hte distant stars.






27. Massive compact halo objects (MACHO) - weakly interacting massive particles (WIMPY's)






28. The 'edge' of the universe. Light beyond this has not reached us yet.






29. The seasonal shifting of a nearby star's position relative to more distant objects.






30. Small moons that maintain the shape of rings around Saturn and Uranus






31. When the Sun moves from south to north across the celestial equator (about March 21)






32. The location in an H-are diagram of a star cluster - where stars have just left the main sequence. Used to estimate the cluster age.






33. 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)






34. Milky way galaxy is a member - a small poor cluster-about 30 galaxies






35. The rate of expansion of the universe.






36. A two-filter measure of the color - and hence temperature - of a star.






37. A high-pressure bulge in Neptune's southern hemisphere






38. 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.






39. Matter so dense that even light cannot escape its gravity






40. Large nebula consisting of very cold gas and dust






41. A small chunk of rock in space






42. Mercury






43. A repeated - periodic push or pull capable of summing into a larger push or pull






44. Hot cells of gas that rise and fall in the hotosphere






45. 100 nm 10 nm






46. Atmosphere blocks high energy wavelengths - atmosphere blurs optical radiation - atmosphere absorbs some radiation at all wavelengths even when it gets through.






47. We can infer the absolute magnitude of pulsating variable stars by measuring their pulsation periods. The longer the pulsations - the greater their luminosities. We then again measure their apparent magnitudes - compare it with their absolute magnitu






48. A large - irregularly shaped rocky object orbiting the sun mostly between mars and jupiter. Left-over planetesimals






49. The class of all objects having high energy radiation coming from their nuclei. Active Galactic Nucleus- Blazars - Quasars - Radio and Emit synchrotron radiation






50. Why do Galaxies move very rapidly in the interiors of the dense clusters?
