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. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the

10. 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)






11. 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






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






13. 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.






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. The movement of rainwater as it filters through soil and rocks into the ground - becoming groundwater






16. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes

19. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






20. Volcanoes are generally found where ________ are diverging or converging






21. Form when dissolved mineral solutions crystalize out of lakes and oceans






22. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






23. Some water infiltrates deep into the ground and replenishes ________ - which store huge amounts of freshwater for long periods of time






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






25. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






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






27. Forms over land and is associated with dry air






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






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






30. Oceans cover __ of the earth's surface






31. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






32. Temperature - pressure - and composition






33. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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






35. Continental tropical (dry - warm air)






36. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)






37. 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






38. The strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






39. Affected by factors such as weathering and impurities






40. Bbreaking along flat surfaces






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

42. When the moon is at first quarter or third quarter - the sun - earth and moon form a 90- degree (right) angle with the earth at the vertex - The combined effect of this alignment of the sun - earth - and moon results in tidal ranges on the earth - Wh






43. 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






44. The cold - water current that flows north to south off the _____________ keeps the West Coast fairly cool during the summer - Cold - water currents create cooler temperatures in areas that would otherwise be much warmer






45. The evaporation of these oceans is how we get most of our __________ - and their temperature determines our climate and wind patterns






46. 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)






47. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment
