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. Centered on the sun.






2. The law that describes the blackbody curve - and let to quantum mechanics.

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






4. 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.






5. Sudden blasts of gamma radiation from a very distant galaxy caused possibly by a supernova explosion.






6. Comglomerates of ice and rock that orbit the sun in highly elliptical paths






7. The gap inthe outer portion of Saturn's A ring






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






9. The oldest grouping of stars - found in the galaxy halo






10. Long - meandering cliff formed when a planet surface cools and shrinks






11. After stars form they pump light energy into surrounding gas causing it to heat up and glow (H2=ionized hydrogen - H1= neutral hydrogen in molcular couds)






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






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






14. What do we think the actual fate of the universe will be and why do we think this?






15. Galaxies whose nuclei emit jets of materil at high speeds. material comes from supermassive black holes






16. The line on an H-are diagram going from upper left to lower right where normal stars of different masses reside.






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






18. The part of the Milky way that has on-going star formation






19. Radiation (possibly left over from the big bang) that fills the universe. Perfect black body spectrum and tells us a bit aout how galaxies are formed.






20. 10^2 nm 10^7 nm






21. The number of protons in an atom.






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






23. Venus (retrograde)






24. Centered on the Earth






25. Stars orvits do not define the spiral patterns - instead they are density waves that move at slower speeds (arms are defined by young O and B stars and gas clouds)






26. Earth






27. The displacement of spectral lines to redder colors caused by the expansion of the universe.






28. That which is responsible for Jupiter's magnetic field






29. How is the Hubble Law consistent with an expanding universe?






30. A subatomic particle with a negative charge. It creates light.






31. A telescope that uses mirrors to focus light






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






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






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






35. Jupiter - Saturn - Uranus - Neptune






36. Medium bulge - moderately would arms - arms have H2 regions in them and look sort of lumpy






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






38. The first rock-sized bodies that formed in the solar nebula from dust grains






39. Jupiter






40. 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.






41. The shadow behind the Earth or Moon where the Sun is partially obscured.






42. 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)






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






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






45. The location of a supermassive black hole






46. Radiation emitted when charged particles spiral rapidly in a magnetic field. come off of jets from black holes.






47. Long - meandering cliff formed when a planet surface cools and shrinks






48. A term referring to the orbital character of stars near the Sun






49. The fusion process that turns three helium nuclei into a carbon nucleus






50. Why do Galaxies move very rapidly in the interiors of the dense clusters?
