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






2. 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.






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






4. A word meaning 'the same everywhere throughout.'






5. 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






6. The Big Bang was not an explosion of matter into empty space - like the explosion of a bomb. Instead - it was an emergence of space and time filled with pure energy where before none of this was present. The point from which is emerged is called the






7. Is there water on the moon?






8. The mix of pure photon energy that emerged at the start of the universe.






9. The shadow area behind the Earth or Moon where the Sun is completely obscured.






10. Jupiter






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






12. The point directly overhead.






13. Distribution of dust (tells us disk is thin) - find distances to O&B stars and H2 regions (arms are sights of star formation and OB stars live and die at location of birth) -Milky way has four arms. Sun is in spur apart from arms.






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






15. Star speed at outer edge of galaxy should begin to diminish - but they dont so we guess that this means there is increasing force (aka dark matter)






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






17. The slow wobble of the Earth on its rotation axis.






18. The organization of clusters of galaxies into sheets and strings






19. The ratio of the actual density of the universe to the critical density. (actual density divided by the critical density






20. When the Moon entirely blocks the Sun.






21. When a planet lines up with the sun inthe sky






22. The place in the sky that the Earth's axis points toward (can be either north or south)






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






24. Centered on the Earth






25. A word used in astronomy to describe all elements besides hydrogen and helium






26. A small and dim but hot star.






27. A cool collection of gas and dust silhouetted against a brighter background of stars and/or gas






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






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






30. In Ptolemy's geocentric solar system - the large circle on which a planet's epicycle moved around the Earth.






31. The powdered stone fragments that make up the lunar 'soil'






32. 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

33. Jupiter






34. An important quality of telescopes that increases as the square of the primary mirror or objective lens






35. Mercury






36. The point directly overhead.






37. A two-filter measure of the color - and hence temperature - of a star.






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






39. When material is heated and moves taking the heat energy with it






40. A star without enough mass to begin hydrogen fusion






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






42. A phenomenon seen when the Earth passes through the orbit of a burned out comet






43. A measure of the force of gravity on an object






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






45. A prominence seen against the disk of the sun






46. The family of radiant energy that includes light as a subset






47. A phenomenon seen when the Earth passes through the orbit of a burned out comet






48. Distribution of dust (tells us disk is thin) - find distances to O&B stars and H2 regions (arms are sights of star formation and OB stars live and die at location of birth) -Milky way has four arms. Sun is in spur apart from arms.






49. The distance light travels in one year (=9.46x10^12km).






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