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.

5. 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 ________.






6. Neptune or uranus






7. 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.






8. Venus






9. IO






10. When particles are compressed to an unnatural state where their pressure is not related to their temperature






11. The state of having a balance between inflowing and outflowing heat-- the temp at every radial point is different but constant






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






13. The process that powers the sun and hydrogen bombs






14. The apparent path of the Sun through the stars on the celestial sphere.






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. A term referring to Earth-like planets






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






18. The rock that makes up the lunar maria






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






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






21. The location in the Milky Way where stars orbit like a solid wheel






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






23. A technique using computer-controlled mirrors to sharpen images distorted by the atmosphere






24. 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






25. A push or a pull






26. The high- temperatature outer layer of the sun






27. An evolved star - past the helium flash that is burning helium to carbon in it's cores






28. A particle of light.






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






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






31. Mercury






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






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

36. A term referring to Jupiter-like planets






37. 1μm 100 nm






38. The name for the only seriously considered theory of the universe.






39. The name for the only seriously considered theory of the universe.






40. Sc galaxies where star formation and destruction is so rapid that supernova explosions are mainly responsible for compressing gas to create new stars.






41. Form honeycomb like patterns surrounding empty or nearly empty voids.






42. A telescope that uses lenses to focus light






43. When one side of a body always faces the planet it revolves around






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






45. Possible Fates of the Universe






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






47. A younger cluster of stars - found in the galaxy disk






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






49. 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.






50. A star that blows itself apart
