CSET Earth

Subjects : cset, 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. Human civilization has lasted only _____ years






3. The process in which one type of rock changes into another






4. The result of the buildup of once - living things






5. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti






6. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms






7. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






8. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






9. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






10. Rocks are placed into groups according to how they form...






11. Forms over water and is associated with wet air






12. Two high waters and two low waters each day - in most locations - tides are semidiurnal






13. Runoff and groundwater are stored as ________ in lakes






14. The motive force behind land breezes and sea/lake breezes - also known as on - or off - shore winds - Land absorbs and radiates heat faster than water - but water releases heat over a longer period of time






15. Improved land - use practices can limit erosion by using techniques such as...






16. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






17. The transformation of water vapor to liquid water droplets in the air - producing clouds and fog






18. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






19. Forms south of the Arctic and is cold






20. The degrees north or south of the equator






21. Affected by factors such as weathering and impurities






22. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






23. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






24. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






25. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






26. Some groundwater finds openings in the land surface and emerges as...






27. Occur along plate boundaries






28. Theory that the earth's continents were originally united as a supercontinent - Pangaea - Established by Alfred Wegener in the early 1900s






29. Not all runoff flows into rivers; much of it infiltrates into the ground through...






30. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






31. The resulting dust layer would act as a shield - blocking out much of the sun's rays - This would result in lower global temperatures and a general _____ of the earth






32. Volcanoes can also form where there is stretching and thinning of the...

33. Faulting and folding






34. Deviates by an angle of approximately 23.5 degrees - Thus - at any given time during summer or winter - one part of the planet is more directly exposed to the rays of the sun - This exposure alternates as the earth revolves in its orbit






35. Center: 3000

36. Oceans cover __ of the earth's surface






37. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






38. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






39. The outermost part of the earth's interior is made up of two layers...






40. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






41. The difference between levels of ocean water at high and low tides






42. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight






43. Around a new or full moon - when the sun - moon - and the earth form a line - the tidal forces due to the sun reinforce those of the moon - The tide's range is at a maximum and is called a spring tide (spring as in 'to jump/leap -' not the season)






44. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






45. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






46. Evaporation often implicitly includes ___________ from plants - although together they are specifically referred to as evapotranspiration
