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






2. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






3. 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






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






5. 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






6. Continental polar (dry - cold air)






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






8. Forms over land and is associated with dry air






9. 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






10. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






11. Formed by sodium chloride






12. 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)






13. Nearest galaxy - about 20 million light - years away






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






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






16. How much matter is in the object






17. The lateral movement of the plates is typically at speeds of ___ mm annually






18. The tidal force produced by the sun is ____ as large as that produced by the moon






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






20. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






21. 1 hour of time






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






23. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






24. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong






25. The runoff produced by melting snow






26. Classified as warm - water or cold - water currents






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






28. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






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






30. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon






31. 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






32. 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






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






34. 186000 miles/second






35. Weather occurs primarily due to density (temperature and moisture) differences between one location and another - These differences can occur due to the angle of the sun at any particular spot - which varies by latitude from the tropics






36. Human civilization has lasted only _____ years






37. A major determiner of coastal climate






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






39. Largest zone of the planet (68%); crystalline silicates - rich in magnesium - calcium - and iron; very hot and mainly solid - but local melting to magma is the source of volcanic eruptions






40. Cirrus - Stratus - Cumulonimbus - Altostratus






41. 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






42. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






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






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






45. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






46. 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






47. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






48. This upslope wind is called a...






49. Featherlike clouds that indicate fair weather






50. Continental tropical (dry - warm air)
