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.
1. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






2. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






3. Forms over land and is associated with dry air






4. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






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






6. Cirrus - Stratus - Cumulonimbus - Altostratus






7. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






8. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






9. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






10. The breakdown of rocks - soils and minerals through atmospheric chemicals or biologically produced chemicals (also known as biological weathering)






11. 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






12. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






13. One tidal cycle per day






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






15. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

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






17. 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






18. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






19. Sometimes called minor planets or planetoids - Bodies






20. Forms over the Tropics and is warm






21. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






22. 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






23. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






24. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






25. Can thaw and melt - and the ensuing water flows overland as snowmelt






26. 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






27. 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






28. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






29. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






30. Somewhat cooler disturbances in the photosphere






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






32. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






33. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






34. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






35. The source of energy for evaporation is primarily through ___________






36. Defined by geometrically subdividing the earth's spheroid into 24 lunes (wedge - shaped sections) - bordered by meridians - each 15






37. The precipitation that is intercepted by plant foliage and eventually evaporates back to the atmosphere rather than falling to the ground






38. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






39. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






40. A major determiner of coastal climate






41. 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)






42. - 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






43. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






44. 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
