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. The runoff produced by melting snow






2. Formed by sodium chloride






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






4. Cause pressure differences - A hot surface heats the air above it and the air expands - lowering the air pressure and its density






5. Take up about 1/3 of the earth's land surface - many are formed by rain shadows - Usually have a large diurnal (day) and seasonal temperature range - with high daytime temperatures






6. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






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






8. The degrees north or south of the equator






9. Forms over water and is associated with wet air






10. Water transpired from plants and evaporated from the soil






11. Affected by factors such as weathering and impurities






12. Occur along plate boundaries






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






14. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra






15. 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.






16. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






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






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






19. The degrees east or west of the prime meridian through Greenwich - England






20. The center of the sun may have a temperature of millions of degrees; the visible surface - the ______ - is about 6000






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






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

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






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






25. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






26. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






27. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






28. One tidal cycle per day






29. There are approx. _____ days between each lunar cycle






30. Large - dark clouds that indicate thunderstorms






31. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






32. 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






33. Center: 3000

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






35. 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)






36. 186000 miles/second






37. Tides may be...






38. The earth is believed to be about ___ billion years old






39. 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






40. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






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






42. 1 hour of time






43. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






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






45. Takes place when the moon passes between the earth and the sun - with the moon blocking the sunlight for about two minutes - A total ___________ may be seen only from a small zone on the earth






46. Comprises one global - interconnected body of salt water often (though generally recognized as several separate oceans) - A continuous body of water with relatively free interchange among its parts






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






48. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






49. 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






50. The strong temperature contrast between polar and tropical air gives rise to the ________
