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 area behind a lens where images are resolved






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






3. A small spherical dark nebula






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






5. Relativity predicts that nothing can travel faster than the speed of light in a vacuum - How can it move slower?






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






7. 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






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






9. Small compact stars called white dwarfs can have material deposited on their surfaces. In time material heats up and explodes in surface nuclear reaction- star brightens - settles - repeats.






10. In a FLAT UNIVERSE(our universe) - the curvature of space-time is ________. Parallel beams will converge/diverge/remain parallel (circle one). The density parameter - Ω0 - is _____.






11. A bridge of material held in position above the solar surface. They can remain for hours even days






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






13. A star that is in the process of forming. It glows from gravitational contraction






14. A fusion process in which a carbon atom transmutes to oxygen and back - creating a helium atom in the process






15. Young clusters in disk are irregularly shaped since they have no time to relax into the rounder relaxed shape of globular clusters-will constantly be torn apart and assimilated.






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






17. The number of protons in an atom.






18. The amount an image is enlarged by a telescope






19. The instant of time after the Big Bang when space and time obtained their characteristics. (t=10^-43 sec when gravity freezes out-instant when gravity started existing as a separate force)






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






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






22. The measure of a variable star's apparent magnitude as it brightens and dims with time






23. A planet that is closer to the sun than the earth






24. The equation that describes how matter equates with energy






25. A very distant - star-like object with huge - broad emission lines. Probably the nucleus of a distant active galaxy.






26. Light-flaky crust - convective currents cause it to wrinkle and bunch (1/5 of surface). uniform cratering suggests lack of weathering and tectonics. volcanoes are flat due to atmospheric pressure.






27. Venus






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






29. What causes the zones and belts on jupiter and saturn?






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






31. The law stating that hotter blackbodies look bluer than cooler blackbodies.

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






33. A very dense - highly populated cluster of galaxies






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






35. Extremely round - lots of liquid water - ice rafts on surface ACTIVE SURFACE






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






37. 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

38. The rotation of a star or planet at different speeds at its equator and poles






39. The surface of the sun






40. The larger bodies that formed early in teh solar nebula that were chemically differentiated






41. A location on an H-are Diagram where evolving stars pulsate






42. Large bulge - tightly wound spiral arms - relatively few h2 regions and are smooth






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






44. The law that syas light energy from a blackbody increases as (temperature^4)






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






46. A star that is in the process of forming. It glows from gravitational contraction






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






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






49. The rock that makes up the lunar maria






50. The measure of a variable star's apparent magnitude as it brightens and dims with time
