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






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






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






4. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






5. 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






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






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






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






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






10. Featherlike clouds that indicate fair weather






11. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






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






14. 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






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






16. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






17. 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






18. 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






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






20. 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






21. One tidal cycle per day






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






23. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






24. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






25. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






26. 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






27. A continuous drill would find gas - oil - and water in that order - The three substances occur in their order of density - with the lightest substance on top and the heaviest on the bottom






28. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






29. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms






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






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






32. 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






33. 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






34. 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






35. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






36. Continental polar (dry - cold air)






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






38. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






39. 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






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

41. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






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






43. Formed by sodium chloride






44. 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






45. 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






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






47. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






48. 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...






49. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






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