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. To preserve & or to avoid wasteful use.






2. A broad & mound-like mass of glacier ice that usually spreads radially outward from a central zone.






3. The generally dark & more or less stable part of the organic matter in a soil & so well decomposed that the original sources cannot be identified.






4. Jupiter is named after the Roman king of the gods. It is the fifth planet from the Sun.






5. Till deposited from main body of glacier during ablation.






6. Bent rock strata.






7. Deposits of wind-borne dust.






8. The seaward edge of coast between low tide and effective wave action.






9. The theory of Plate Tectonics states that the Earth's crust is fragmented into a dozen or more large and small pieces floating on a semi-molten mantle.






10. Water that flows across watersheds during and immediately after severe rainstorms. In populated areas & stormwater runoff is often water that cannot be handled by existing sewer systems. Stormwater runoff is the leading source of water pollution in t






11. Deserts in zones of descending air between 25 degrees and 30 degrees north and south latitude.






12. The areas of & in & or constituting a city.






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






14. The very small particles of dirt & soot & and other pollutants that are present in the air.






15. Bent rock strata.






16. A rock that has crystallized from a molten state.






17. A large & basin-shaped volcanic depression & more or less circular in form. Typically steep-sided & found at the summit of a shield volcano.






18. An atmospheric shield providing the Earth with protection from ultra-violet rays which can cause sun burn & skin cancer and the destruction of the delicate plant life which supports the planet's food chain.






19. The process by which an unconsolidated deposit of sediments is converted in to solid rock.






20. A soft compact calcite & CaCO3 & with varying amounts of silica & quartz & feldspar & or other mineral impurities & generally gray-white or yellow-white and derived chiefly from fossil seashells.






21. The region of a shore that is covered at high tide and exposed at low tide.






22. A thick layer of soil.






23. The process by which building stone & usually in blocks or sheets & is extracted from the Earth. radiation -- (Electromagnetic radiation) -- energy that travels through space in the form of waves without the intervention of matter & as in the transp






24. The speed at which water flows.






25. To change back and forth uncertainly.






26. Any seismic wave that travels through the body of Earth & rather than along its surface.






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






28. A zone in the Earth between 400 and 670 km below the surface separating the upper mantle from the lower mantle.






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






30. The closest star to Earth besides the sun. It is approximately 4 light years away.






31. The very slow & generally continuous downslope movement of soil and debris under the influence of gravity.






32. No identifiable layers of minerals in a rock sample






33. Living parts of the environment that can renew or replace themselves.






34. Mars is named after the Roman god of war. It is the fourth planet from the Sun.






35. A large ridge or mound-like structure within a body of water that is built by calcareous organisms such as corals & red algae & and bivalves.






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






37. Water beneath the Earth's surface.






38. Either the northern or southern half of the Earth as divided by the equator & or the eastern or western half as divided by a meridian.






39. A vent in the surface of the Earth & from which lava & ash & and gases erupt.






40. The area bordering a stream over which water spreads when the stream tops its channel banks.






41. Elongated rises on the ocean floor where basalt periodically erupts & forming new oceanic crust.






42. A small ice sheet.






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






44. A study designed to collect critical data to be used for comparison or as a control in a later study.






45. A wall built out from the shore & usually at perpendicular to it to trap sand carried by longshore currents .






46. A lake in an abandoned meander.






47. A continuous well-defined mass of material of sufficient ore content to make extraction economically feasible. compare mineral deposit.






48. A large area of flat or nearly flat land.






49. Property possessed by certain rocks of breaking with relative ease along parallel planes or nearly parallel surfaces in their crystal structures where the bonds are weakest.






50. A sea level change due to change in load on Earth's crust.
