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 rock that makes up the lunar highlands






2. A star without enough mass to begin hydrogen fusion






3. The point in its orbit where a planet is farthest from the sun






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






5. A particle of light.






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






7. When material is heated and moves taking the heat energy with it






8. Flat disk with gas - dust - H2 regions - molecular clouds - dust young stars and remnants of old planetary nebula and supernova remnants. stars spin together with similar velocities called differential rotation






9. Europa






10. In a CLOSED UNIVERSE - the curvature of space-time is _________. Parallel beams will converge/diverge/remain parallel (circle one). The density parameter - Ω0 - is _____.






11. Matter that reveals itself only through its gravitational attraction






12. The mass of an object divided by its volume






13. The universe is isotropic - homogeneous - and without beginning or end in time and space. If the universe is truly homogeneous then every line of sight will eventually end on a galaxy. If it has existed forever then there has been enough time for lig

14. 10 nm 10^2 nm






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






16. The mass of an object divided by its volume






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






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






19. Ancient stream channels - flood planes - and sedimentary-type rock. Frozen water is found in the polar ice caps and in the soil.






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






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






22. The point in its orbit where a planet is nearest the sun






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






24. Originially thought to be stars emitting radio radiation but are now concluded to be nuclei of distant galaxies (same as radio galaxies aka emit streams of material)






25. The rate of expansion of the universe.






26. A planet orbiting about a distant star






27. The number of protons in an atom.






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






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






30. Ganymede and Titan






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






32. Why does the earth have few craters while the moon has many?






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






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






35. 1μm 100 nm






36. The oldest terrain on the moon






37. A highly variable galaxy nucleus of which BL Lac is one. Their light is highly energetic and their spectra are featureless. (face on)






38. 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

45. The rock that makes up the lunar maria






46. Neptune or uranus






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






48. Loops that trace the magnetic field as it erupts from a sunspot area and arches over to an adjacent area. They glow in the light of gas pouring out of corona and falling into photosphere.






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






50. A galaxy emitting large amounts of energy at long wavelengths.
