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.

2. Neptune or uranus






3. Jupiter






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






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






6. The process that powers the sun and hydrogen bombs






7. A small and dim but hot star.






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






9. Cold aggregates of gas - large and contain a huge amount of matter - so cold that molecules stick together to form molecules.






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






11. The rock that makes up the lunar maria






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






13. A crystalline patter found in iron meteorites






14. A small chunk of rock in space






15. The study of the universe as a whole.






16. The mass of an object divided by its volume






17. A rock or iron specimen that has fallen from space






18. Elliptical orbits that come inside orbit of the Earth.






19. The process of acquiring material






20. That which is responsible for Jupiter's magnetic field






21. The science of measuring the apparent magnitudes of stars by imaging them through different filters.






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






23. Hydrogen and helium (mainly)






24. A streak of light in the atmosphere






25. Sc galaxies






26. Dark areas on the sun that are cooler than the surrounding photosphere






27. Galaxies whose nuclei emit jets of materil at high speeds. material comes from supermassive black holes






28. A planet orbiting about a distant star






29. The lens in a telescope used to determine the magnification






30. The amount an image is enlarged by a telescope






31. Saturn






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






33. Any class of objects with a uniform luminosity used to determine distance.






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






35. What are the three possible geometries of the universe?






36. The 11 or 22 period on the sun durin which sunspots increase - decrease - change polarity - increase and decrease again.






37. Largest moon in solar system - two differenet types of terrain - darker terrain is older - NOT ACTIVE SURFACE






38. Centered on the sun.






39. Mercury






40. A large and bright but cool star.






41. A measure of the ability of a telescope to see fine detail






42. The apparent backward motion of a planet against the background of stars.






43. A star that has become a red giant for the second and final time. It is burning helium to carbon in a shell surrounding the core






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






45. Dying small mass stars lose their outer layers in a relatively gentle way - creating a round or bipolar nebula about the star (round like planets)






46. Ganymede and Titan






47. 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.






48. Any change in the speed or direction of an object's motion






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






50. Plate tectonics due to thickness of crust and maintain their general form when they collide-where most volcanoes are.
