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. Mercury






2. The study of the universe as a whole.






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






4. Mercury






5. Dark areas on the sun that are cooler than the surrounding photosphere






6. Radiation given off by electrons accelerating in a magnetic field






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 rotation period of the Earth measured relative to the stars.






9. The material from which the solar system formed






10. Theory virtually demands that the geometry of the universe be ______. Results of measuring lumps in the cosmic background radiation indicate that the universe geometry is ________.






11. A spherical shell of comets that orbit the sun at a great distance (roughly two light years from the sun)






12. The mass of an object divided by its volume






13. 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

14. IO






15. The faint glow of light left over from the Big Bang. cosmic microwave background are the photons that remain after the big bang that have not turned into matter.






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






17. A measure of the ability of a telescope to see fine detail






18. Jupiter






19. The force of attraction between any two objects having mass






20. The point in its orbit where a planet is nearest the sun






21. The sinking of denser elements to the center of a young molten planet






22. The science of measuring light energy by wavelength.






23. The era when the ratio of matter to energy greatly favored matter. (verses radiation dominated universe where it was opaque. Matter is now dominated by gravity not photons)






24. The gap etween saturn's A and B rings






25. A particle of light






26. Dying large-mass stars lose their outer layers in a violent explosion creating large - chaotic remnants. these brighten like nova but are so much brighter and only occur ONCE PER STAR






27. How did Earth come to have an oxygen rich atmosphere?






28. Infinitely long -> 10 cm






29. 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.






30. 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)






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






32. 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.






33. The amount of density needed to stop the universe from expanding and to begin the big crunch represented by Pc






34. The force of attraction between any two objects having mass






35. When the Sun is farthest south of the celestial equator (About December 22)






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






37. In a CLOSED UNIVERSE - the curvature of space-time is _________. Parallel beams will converge/diverge/remain parallel (circle one). The density parameter - Ω0 - is _____.






38. The elementary building blocks from which protons and neutrons are formed.






39. 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)






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






41. 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






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






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






44. The science of measuring the apparent magnitudes of stars by imaging them through different filters.






45. A streak of light in the atmosphere






46. Venus

48. Half of the longest diameter across an ellipse






49. A fusion process in which protons build together to form helium
