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. Electromagnetic Radiation






2. Approximate speed of light in a vacuum






3. When the Moon entirely blocks the Sun.






4. The area behind a lens where images are resolved






5. Small bulges - loosely wound - massive arms - arms have many H2 regions and look very lumpy






6. A bright area of higher temperature that often proceeds the formation of sunspots.






7. Venus






8. The dimming of starlight by intervening dust






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






10. Finding a star's absolute magnitude from it's placement on an HR diagram. After finding the absolute magnitude - we measure the apparent magnitude - for a distance modulus and use this to find the distance. This method is good for finding distances t






11. An energetic event taking place in the early universe






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






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






14. The assumption that the universe is isotropic (same in all directions) and homogeneous (Same everywhere throughout)






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






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






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






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






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






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






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






22. Centered on the sun.






23. The time when the universe cooled sufficiently for atoms to exist. radiation dominated= first 300000 years - THEN era of recombination turns into matter dominated for next.






24. 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.






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






26. 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)






27. When the Sun is farthest north of the celestial equator (about June 22)






28. A change in the wavelength of light caused by a motion between the observer and light (or wave) source (blue shift if getting closer - red shift if moving away)






29. 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)






30. A location on an H-are Diagram where evolving stars pulsate






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






32. Norhern lowlands- darker in color and have far fewer craters as if an ancient sea or ice field covered them. southern highlands- much higher in density of craters.






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






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






35. Formed from slow rotating clouds - collapsed quicker - initial star formation rate is high but died out - older - little rotation - look redder






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






37. The dark - relativley smooth areas on the moon; Latin for sea






38. A collection of galaxies like the one the Milky Way belongs to






39. A very dense - highly populated cluster of galaxies






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






41. VENUS






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






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






44. A high-pressure bulge in Neptune's southern hemisphere






45. The Greek philosopher responsible for making the stellar magnitude scale.






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






47. A small spherical dark nebula






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






49. 100 nm 10 nm






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