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. Places in the asteroid belt - caused by resonance with Jupiter - where there are no asteroids

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






10. The act of removing an electron from an atom.






11. The rotation period of the Earth measured relative to the stars.






12. The point directly overhead.






13. An evolved star - past the helium flash that is burning helium to carbon in it's cores






14. A star fusing hydrogen to helium in it's core






15. A nearby galaxy with a quasar-like nucleus. closer but less bright than quasars-weaker






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






17. Material that shoots rapidly out into space. Flares cause Auroras






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






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






20. The temp at which a substance in the vacuum of space solidifies






21. Ganymede and Titan






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






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






24. An object that may remain after a star explodes






25. A star that has become a red giant for the second and final time. It is burning helium to carbon in a shell surrounding the core






26. Sa - Sb galaxies where two magnificent arms wind their way from nucleus out in a symmetrical manner.






27. The rock that makes up the lunar highlands






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






29. The wavelengths where a specific element can absorb or emit light.






30. Sc galaxies






31. A younger cluster of stars - found in the galaxy disk






32. Highlands: rocks are made of lighter anorthosite (similar to old earth rocks) Maria: rocks made of heavy mare basalt (volcanic rock) everywhere else is loose regolith created by meteoric impact.






33. Dying small mass stars lose their outer layers in a relatively gentle way - creating a round or bipolar nebula about the star (round like planets)






34. The state of having a balance between inflowing and outflowing heat-- the temp at every radial point is different but constant






35. Jupiter






36. The lens in a telescope used to determine the magnification






37. The 11 or 22 period on the sun durin which sunspots increase - decrease - change polarity - increase and decrease again.






38. The dimming of starlight by intervening dust






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






40. 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






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






42. The apparent magnitude a star would have if it were at a distance of 10 parsecs.






43. The high- temperatature outer layer of the sun






44. A push or a pull






45. The location of a supermassive black hole






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






47. A method of finding a star's distance from its absolute magnitude and spectral type or color.






48. Any change in the speed or direction of an object's motion






49. When the Sun is farthest north of the celestial equator (about June 22)






50. A star that blows itself apart
