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. Biochemical sedimentary rock; it's made from cryptocrystalline quartz. Examples - flint and jasper.






2. Equant - meaning that they have the same dimensions in all directions. Or inequant - meaning their dimensions are not the same in all directions.






3. Rock formations still attached to the Earth's crust.






4. Type of volcanic eruption; pyroclastic - produce clouds and avalanches of pyroclastic debris. Gas expands in the rising magma - cannot escape. The pressure becomes so great that it blasts the lava - and volcanic rock - out of the volcano.






5. A mineral's growth that is uninhibited - has well-formed crystal faces.






6. The distance of the deepest well ever drilled - hole in northern Russia. Penetrates only about 0.03% of the Earth.






7. Mineral group; olivine group - pyroxene group - amphibole group.






8. A single - continuous (uninterrupted) piece of a crystalline solid bounded by flat surfaces called crystal faces that grew naturally as the mineral formed. Come in a variety of shapes - cubes - trapezoids - pyramids - octahedrons - hexagonal columns






9. The removal of soil by running water or by wind.






10. Mineral crystal formation type; form by type of diffusion - the movement of atoms or ions through a solid to arrange into a new crystal structure; process takes place very slowly.






11. The most important mineral group; comprise the most rock-forming minerals - they are very abundant due to large % of silicon and oxygen in Earth's crust. Examples - oxygen - silica - aluminum.






12. Cause of melting; when magma rises up from the mantle into the crust - it brings heat with it which raises the temperature of the surrounding crustal rock - and in some cases melting occurs.






13. Lava flow; associated with felsic magma - consists of ash and pumice fragments - material is propelled from the vent at a high speed.






14. Refers to the arrangement of grains in a rock; that is - the way the grains connect each other and whether inequant grains are aligned parallel to one another.






15. A process occurring when the sea level rises - the coast migrates inland. Through this - an extensive layer of beach forms.






16. Places where intrusive igneous rock creates tabular intrusions cutting across rock that does not have layering - this nearly vertical - wall-like tabular intrusions is formed. Cut across layering within the earth.






17. Magma is less dense than surrounding rock - and thus is buoyant. Magma is less dense both because rock expands as it melts and because magma tends to contain smaller proportions of heavy elements. Also - magma rises because the weight of overlying ro






18. Process occurring after sediment has been compacted - can then be bounded together to make coherent sedimentary rock. Binding material consists of minerals (commonly quartz or calcite).






19. A distinctive sequence of strata traced across a fairly large region. For example - a region may contain a succession of alternating sandstone and shale beds deposited by rivers - overlain by beds of marine limestone deposited later.






20. A type of soil consisting of about 10-30% clay and the rest silt and sand. Pores remain between grains so that water and air can pass through and roots can easily penetrate.






21. Solids composed of metal atoms (such as iron - aluminum - copper - and tin). Within this type of solid - outer electrons are able to flow freely.






22. Elongate submarine mountain ranges whose peaks lie only about 2-2.5km below sea level. Consist of a ridge axis - are roughly symmetrical - and can include escarpments - axial troughs - and valleys. Examples - Mid-Atlantic Ridge - East Pacific Rise -






23. Distinct internal laminations within a ripple or dune that are inclined at an angle to the boundary of the main sedimentary layer. Form as a consequence of the evolution of dunes or ripples.






24. A cut and finished stone ready to be used in jewelry. Examples - diamond - ruby - sapphire - emerald.






25. Process where a convergent boundary ceases to exist when a piece of buoyant lithosphere - such as a continent or island arc - moves into the subduction zone. Yield some of the most spectacular mountains/mountain ranges on the planet including the Him






26. Highest soil horizon; consists almost entirely of organic matter and contains barely any mineral matter. Surface level has 'litter' and deeper it contains 'humus'. Part of the zone of leaching.






27. The bottom portion of the upper mantle - the interval lying between 400km and 660km deep. Here within the Earth - the character of the mantle undergoes a series of abrupt changes.






28. Magma type; contains about 66% to 76% silica. Name reflects the occurrence of feldspar and quartz in rocks formed in this magma.






29. Rock made by the freezing of magma underground - after it has pushed its way (intruded) into preexisting rock of the crust.






30. An ultramafic rock with large grains. intrusive - phaneritic igneous rock.






31. Consists of rock and sediment that has been modified by physical and chemical interaction with organic material and rainwater - over time - to produce a substrate that can support the growth of plants.






32. A name for any kind of unconsolidated debris that covers bedrock. Includes both soil and accumulations of sediment that have not evolved into soil.






33. The broad - relatively flat regions of the ocean that lie at a depth of about 4-5km below sea level.






34. A pluton formation theory; a process during Which magma assimilates wall rock - and blocks of wall rock break off and sink into the magma.






35. Active hot-spot volcanoes commonly occur at the end of a chain of dead volcanoes.






36. Two different minerals which have the same composition but have different crystal structures.






37. A fine spray of lava instantly freezes to form fine particles of glass.






38. Process that occurs after the sediment has been buried - pressure cause by the overburden squeezes out water and air that had been trapped between clasts - and the clasts press together tightly.






39. A vent at Which melt from inside the Earth spews onto the planet's surface. Erupt.






40. When silt and clay accumulate in the flat areas bordering a stream - lagoon - or delta - the silt when lithified becomes this type of sediment. And the mud - when lithified - becomes another type of sediment - also known as shale.






41. Type of magma; low in silica - fluid - crystallize at high temperatures.






42. Mineral class; the anion within these types of minerals is a halogen ion (such as chlorine or fluorine).






43. Forms from a chemical reaction between solid calcite and magnesium-bearing groundwater.






44. Blocks of rock that are solid and durable but composed of rough quartz sand grains cemented together.






45. The boundary between two beds is a bedding plane; several beds constitute this structure.






46. Physical property of a mineral; a measure of a minerals relative ability to resist scratching - and therefore represents the resistance of bonds in the crystal structure being broken. The atoms or ions in crystals of a hard mineral are more strongly






47. Sedimentary rock composed of clay.






48. If a stoped block does not melt entirely - but rather becomes surrounded by new igneous rock - it becomes this; xeno - meaning foreign.






49. The transformation of loose sediment into solid rock.






50. Chemical weathering occurring in warm - wet climates can produce a layer of rotten rock - over 100km thick.
