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. Forms over water and is associated with wet air






2. 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






3. This upslope wind is called a...






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






5. Faulting and folding






6. Water transpired from plants and evaporated from the soil






7. The science of the atmosphere and weather






8. 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






9. Scientists theorize that massive volcanic eruptions on a global scale contributed to the earth's cooling - resulting in the onset of the...






10. Forms south of the Arctic and is cold






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






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






13. Temperature - pressure - and composition






14. Occur along plate boundaries






15. Refers to the long - term weather patterns of a large geographical area and takes into account temperature - humidity - and precipitation






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






17. Large - dark clouds that indicate thunderstorms






18. 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)






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






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






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






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






23. 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






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






25. Somewhat cooler disturbances in the photosphere






26. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






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






28. Maritime tropical (wet - warm air)






29. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






30. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






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






32. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






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






34. Runoff and groundwater are stored as ________ in lakes






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






36. Affected by factors such as weathering and impurities






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






38. 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






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






40. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






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






42. Smooth layers of low clouds that indicate a chance of drizzle or snow






43. 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






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






45. The runoff produced by melting snow






46. Seas - gulfs - bays - and other names






47. 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






48. One tidal cycle per day






49. Characterized by similar temperatures and moisture levels






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