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. Mercury is named after the Roman messenger of the gods. It is the closest to the Sun.






2. Soil conditions prevailing in area whose mean annual temperature is 0o C.






3. Verifying assessments made from satellite data by doing direct & 'on-the ground' measurements.






4. Igneous. Antonym of intrusive. Synonym of volcanic. Pertaining to igneous rocks or features formed from lava released on the Earth's surface.






5. A statement of relative age in layered rocks: In a series of sedimentary rocks that has not been overturned & the topmost layer is always the youngest and the bottommost layer is always the oldest.






6. An icicle-shaped accumulation of dripstone hanging from cave roof.






7. An instrument that detects & magnifies & and records vibrations of the Earth & especially earthquakes.






8. To preserve & or to avoid wasteful use.






9. The average weather conditions of an area over many years & as measured by temperature & wind speed & and precipitation.






10. Heat extracted from the Earth for use as an power source.






11. The innermost zone of Earth. It consists of two parts & an outer liquid section and an inner solid section & both chiefly of iron and nickel with about 10 percent lighter elements. It is surrounded by the mantle.






12. The presence of layers in some rocks caused by parallel alignment of minerals.






13. A process of land degradation initiated by human activity & particularly in the zones along the margins of deserts.






14. A large amount of gas and dust in space & spread out in an immense volume.






15. A blanket of wind-driven sand with an upper surface about a meter above ground level.






16. Fossils formed when water containing minerals leaks into a mold. The minerals harden to form a copy of the original structure or organism.






17. A system involving continuous interaction of the solid Earth & the atmosphere & the oceans and living things.






18. Mountains & characterized by extensive folding and thrust faulting & that form at convergent plate boundaries on continents.






19. (Latin- Terra & Greek- Gaia) Earth is named after the ancient Germanic Goddess of the soil. It is the third planet from the Sun.






20. The principle that states the processes operating to change the Earth in the present also operated in the past.






21. A slide involving a downward and usually sudden movement of newly detached segments of bedrock sliding or slipping over an inclined surface of weakness such as a bedding plane & fault plane & or joint surface.






22. The partial or complete blocking from view of one object by another.






23. The precipitation that runs directly off the surface to stream or body of standing water.






24. A pillar formed as a stalactite and stalagmite meet.






25. Heat transport by direct transfer of energy from one particle to another & without moving the particle to a new location.






26. A tool for measuring the relative clarity of water.






27. Any natural concentration of a valuable material in the Earth's crust & whether that material can be extracted profitably or not.






28. Ratio between weight of given volume of material and weight of equal volume of pure water.






29. A large volume of dust-sized particles lifted high into the atmosphere.






30. A reverse fault on which the dip angle of the fault plane is 15 degrees or less.






31. A division of geologic time next smaller than the eon and larger than a period. Example: The Paleozoic era is in the Phanerozoic eon and includes & among others & the Devonian period.






32. A spring whose temperature is 6.5o C or more above mean annual air temperature.






33. A division of geologic time next shorter than a period. Example: the Pleistocene epoch is in the Quaternary period.






34. The perpendicular or very steep descent of a stream.






35. A group of stars that appear to make a pattern in the sky. The Big Dipper is a constellation.






36. A worldwide change in sea level & such as caused by melting glaciers.






37. The rigid outer shell of the Earth. It includes the crust and uppermost mantle and is on the order of 100 km in thickness.






38. A low & nearly flat accumulation of sediment deposited at the mouth of a river or stream & commonly triangular or fan-shaped.






39. Any object that revolves around another object in space.






40. A person who makes maps.






41. The mass of an object divided by its volume.






42. A tool for measuring the relative clarity of water.






43. A small & dust-bearing whirlwind.






44. An individual grain or constituent of a rock.






45. The sum of the processes that result in the wearing away or the progressive lowering of the Earth's surface by weathering & erosion & mass wasting & and transportation.






46. Open pit mining & typically for coal.






47. Swamp that forms in the low lying flood plain behind a levee.






48. The great circle on the Earth's surface passing through The North and South Poles & which is considered 0 degrees longitude. The prime meridian passes through Greenwich & England & and is used as a reference point for measuring longitude east and w






49. Heat transport by moving particles & and the thermal energy that they carry & to a new location.






50. Containing moisture.
