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 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

4. Then the Sun moves from north to south across the celestial equator (about September 23)






5. VENUS






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






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






8. An element of a highly efficient - two-dimensional electronic light detector






9. A spread of light with an uninterrupted wavelength distribution of energy.






10. A streak of light in the atmosphere






11. Orbit in Jupiters orbit






12. The crust of a meteorite caused by its entry into Earth's atmosphere






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






14. 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






15. Elliptical orbits that come inside orbit of the Earth.






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






17. Rich= dense crowded cores of galaxies - poor= few members and a looser organization of galaxies






18. The time when the universe cooled sufficiently for atoms to exist. radiation dominated= first 300000 years - THEN era of recombination turns into matter dominated for next.






19. A small chunk of rock in space






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






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






22. A galaxy emitting large amounts of energy at long wavelengths.






23. An element of a highly efficient - two-dimensional electronic light detector






24. Old - pock marked - icy surface - interior is not differentiated - geologically dead - NOT ACTIVE SURFACE






25. A change in the wavelength of light caused by a motion between the observer and light (or wave) source (blue shift if getting closer - red shift if moving away)






26. Flat disk with gas - dust - H2 regions - molecular clouds - dust young stars and remnants of old planetary nebula and supernova remnants. stars spin together with similar velocities called differential rotation






27. A point in the sky where meteors appear to come from during a shower






28. 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)






29. Venus






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






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






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






33. Possible Fates of the Universe






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






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






36. The study of the universe as a whole.






37. Jupiter






38. All wavelengths of light emitted by a blackbody.






39. 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.






40. Extends to a distance of 50000AU. Same objects as in the Kuiper belt-when they fall in toward the sun they become comets. Debris from comets hitting the Earths atmosphere cause meteor showers.






41. 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.






42. What are the three possible geometries of the universe?






43. The study of the universe as a whole.






44. Elliptical orbits that come inside orbit of the Earth.






45. A distance measure determined by the shifting of a star against the background sky every 6 months.






46. A force exerted by reflecting sunlight






47. An empirical scheme for predictin ghe orbital distances of planets






48. A plot of star absolute magnitude verses spectral type.






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






50. The mirror that determines the focus configuration of a reflector
