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. A plot of star absolute magnitude verses spectral type.






2. A telescope that uses mirrors to focus light






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






4. 1 mm 1μm






5. Disk dust grains are made of all the elements that are not in gaseous form in space which blocks starlight and causes interstellar extinction






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






7. The particle horizon is the farthest we can see. It exists because the universe had a beginning and thus a definite age. Light from distances farther away from the particle horizon have not had time to reach us yet.

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






11. Large nebula consisting of very cold gas and dust






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






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






14. 30AU to 50Au from sun - consists of ancietn premordial objects made of frozen ice and dust-35000 objects or more that are larger than 100 km in diameter and many more smaller than this






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






16. A force exerted by reflecting sunlight






17. IO






18. The rock that makes up the lunar highlands






19. The distance between a lens and its focal plane






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

21. When the Sun is farthest south of the celestial equator (About December 22)






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






23. Saturn






24. The average distance between the Earth and the Sun (=1.5 x10^8km)






25. 1. We see rapid movements or high energy radiation coming at some level from the nuclei of nearly every galaxy we have looked at. 2. We suspect that the creation of these supermassive black holes is part of the galaxy formation process.






26. A large - irregularly shaped rocky object orbiting the sun mostly between mars and jupiter. Left-over planetesimals






27. Sa - Sb galaxies where two magnificent arms wind their way from nucleus out in a symmetrical manner.






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






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






30. 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

31. A planet orbiting about a distant star






32. A change in the appearance of the sun at the edge of the solar disk






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






34. Very center of galaxy. suggestion of a black hole






35. Is there water on the moon?






36. Places in the asteroid belt - caused by resonance with Jupiter - where there are no asteroids

39. The north-south line passing directly overhead through the zenith.






40. In what chemical form are jupiters nitrogen - carbon and oxygen?






41. The apparent magnitude a star would have if it were at a distance of 10 parsecs.






42. Material that shoots rapidly out into space. Flares cause Auroras






43. What is the universe expanding into?






44. A push or a pull






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






46. 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.






47. Europa
