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 layer of the sun just above the photosphere






2. A logarithmically scaled value for the measured brightness of a star.






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






4. A representation of the changes in color and brightness of an evolving protostar.






5. Jupiter






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






7. Latin for 'cloud'. A word used to describe the collections of gas and dust in the Milky Way and other galaxies






8. A huge sphere of tenuous gas surrounding the nucleus of a comet






9. The process responsible for creating the arms of flocculent spiral galaxies






10. Ganymede and Titan






11. The opaque universe that existed for 300000 years after the Big Bang. (photons outnumbered nuclei by 1 billion to one - so less light)






12. When massive objects bend space and time enough to create multiple images of an object located behind them






13. What Ole Roemer used to measure the speed of light in a vacuum






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






15. Poitns of gravitational stability in the orbit of a planet






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






17. Sulfurous volcanoes - pools of liquid sulfur - surface resembles cheese pizza ACTIVE SURFACE






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






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






20. The linear correlation between the rate of the expansion of the universe and distance. Says that as galaxies get farther away in space - the speed with which they recede from us increases. So we can measure the amount of recessional velocity and use






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






22. A term referring to Earth-like planets






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






24. Sulfurous volcanoes - pools of liquid sulfur - surface resembles cheese pizza ACTIVE SURFACE






25. The cosmological principle is the assumption that the universe is isotropic and homogeneous.The Big Bang assumes it to be a correct principle so that what we observe is exactly like What is too far away to be observed.






26. A repeated - periodic push or pull capable of summing into a larger push or pull






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






28. The fate of the universe if it is closed. The universe expanding as much as possible and then retracting






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






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






31. 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.






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






33. A toroidal or donut-shaped collection of material attracted to a central body like a star or black hole. Dust around an object






34. Dark - reddish - low-pressure bands in Jupiter's atmosphere






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






36. A massive variable star used to find distances to the galaxies or clusters that contain them.






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

38. An empirical scheme for predictin ghe orbital distances of planets






39. The rotation period of the Earth measured relative to the Sun.






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






41. A perfect absorber and radiator of electromagnetic radiation.






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






43. Sc galaxies






44. Mercury - Venus - Earth - Mars






45. Light scattered through the atmosphere that degrades astronomical images






46. Jupiter - Saturn - Uranus - Neptune






47. A perfect absorber and radiator of electromagnetic radiation.






48. Large nebula consisting of very cold gas and dust






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






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