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






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






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






4. A crystalline patter found in iron meteorites






5. Either Io -Europa - Ganymede - or Callisto






6. The movement of the Earth's crustal plates riding on top of the mantle.






7. Latin for 'cloud'. A word used to describe the collections of gas and dust in the Milky Way and other galaxies






8. Sc galaxies where star formation and destruction is so rapid that supernova explosions are mainly responsible for compressing gas to create new stars.






9. A force exerted by reflecting sunlight






10. Jupiter






11. Plate tectonics due to thickness of crust and maintain their general form when they collide-where most volcanoes are.






12. The distance a moon can be from a planet before shattering from tidal forces






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






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






15. The process similar to conduction by which energy moves from the solar core to the convective layer






16. Light scattered through the atmosphere that degrades astronomical images






17. A spinning neutron star






18. The trapping of heat by carbon dioxide or other gases in the Earth's atmosphere.






19. A collection of comets in the plane of the solar system - located beyond the orbit of Pluto






20. Is space infinitely large?

21. 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

22. A cloud of ionized hydrogen. Formed when young stars heat the surrounding gas






23. Form honeycomb like patterns surrounding empty or nearly empty voids.






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






25. A volume of space where few - if any - galaxies are located






26. Originially thought to be stars emitting radio radiation but are now concluded to be nuclei of distant galaxies (same as radio galaxies aka emit streams of material)






27. 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






28. A long-lived high-pressure bulge in Jupiter's southern hemisphere






29. The Big Bang says that the universe has not existed forever. It had a distinct beginning about 14 billion years ago called the 'Big Bang'. Therefore light from any object more than 14 billion light years away has not had time to reach us. The other p

30. The state of having a balance between inward and outard pressures in a gas--the inward force from gravity is balanced by the outward force from heat.






31. 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.






32. The point where an inferior planet is as far away from the sun as it can be (as seen from the Earth)






33. Thick rigid crust - no longer has plate tectonics but still has convective hot spots that create earth-like volcanoes except that last for billions of years because of lack of tectonics.






34. The point in its orbit where a planet is farthest from the sun






35. The fate of the universe if it is closed. The universe expanding as much as possible and then retracting






36. In Ptolemy's geocentric solar system - the small circle on which a planet moved.






37. The point directly overhead.






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






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






40. Poitns of gravitational stability in the orbit of a planet






41. Stars fromt he Halo that have drifted into the disk. as earth zooms past them in a faster orbit they appear to be going backward very fast






42. A volume of space where few - if any - galaxies are located






43. Europa






44. A star that erratically and explosively brightens and dims






45. The entity responsible for spiral arms in grand-design spiral galaxies






46. The trapping of heat by carbon dioxide or other gases in the Earth's atmosphere.






47. The Big Bang says that the universe has not existed forever. It had a distinct beginning about 14 billion years ago called the 'Big Bang'. Therefore light from any object more than 14 billion light years away has not had time to reach us. The other p

48. The entity from which the whole universe is postulated to have come from.






49. The equation that describes how matter equates with energy






50. 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)
