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 amount an image is enlarged by a telescope






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






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






4. The process that powers the sun and hydrogen bombs






5. The study of the universe as a whole.






6. A cloud of ionized hydrogen. Formed when young stars heat the surrounding gas






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






8. The equation that describes how matter equates with energy






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


10. A measure of the force of gravity on an object






11. 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.






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






13. Moon in less than the angular diameter of the Sun.






14. 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


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






16. A very distant - star-like object with huge - broad emission lines. Probably the nucleus of a distant active galaxy.






17. An energetic event taking place in the early universe






18. Hurricane-like vortex in southern-hemisphere winds to north and south blow in opposite directions which keep it spinning and with no subsurface features like mountians it persists.






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






20. The location in the Milky Way where stars orbit like a solid wheel






21. A spinning neutron star






22. An efficient - two-dimensional electronic light detector. Common in digital cameras - they revolutionized astronomical imaging






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






24. The 'edge' of the universe. Light beyond this has not reached us yet.






25. The nuclei of very distant galaxies. Likely a manifestation of supermassive black holes






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






27. A planet orbiting about a distant star






28. A cloud of ionized hydrogen. Formed when young stars heat the surrounding gas






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






30. A faint - remarkably uniform distribution of radiation in space






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






32. A long-lived high-pressure bulge in Jupiter's southern hemisphere






33. Saying that the sky should not get dark at night because all lines of sight end on a star meaning that the night sky should be ablaze BUT the big bang - because the universe had a beginning - says that the sky gets dark because out in space - galaxie


34. The law that describes the blackbody curve - and let to quantum mechanics.


35. Venus






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






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






38. A technique using computer-controlled mirrors to sharpen images distorted by the atmosphere






39. A small chunk of rock in space






40. The point where a superior planet is as far away from the sun as it can be (as seen from the Earth)






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






42. Long - meandering cliff formed when a planet surface cools and shrinks






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






44. A crystalline patter found in iron meteorites






45. 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.






46. The rotation of a star or planet at different speeds at its equator and poles






47. A word meaning 'the same everywhere throughout.'






48. Neptune or uranus






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






50. A distance measure determined by the shifting of a star against the background sky every 6 months.
