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. 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






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






3. 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






4. 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)






5. 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






6. Affected by factors such as weathering and impurities






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






8. Bbreaking along flat surfaces






9. Large - dark clouds that indicate thunderstorms






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






11. Temperature - pressure - and composition






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






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






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. Oceans cover __ of the earth's surface






16. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






17. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






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






19. 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






20. 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






21. The science of the atmosphere and weather






22. 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






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






24. One tidal cycle per day






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






26. Runoff and groundwater are stored as ________ in lakes






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






28. Cirrus - Stratus - Cumulonimbus - Altostratus






29. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






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






31. Somewhat cooler disturbances in the photosphere






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


33. Forms over the Tropics and is warm






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






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






36. 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






37. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






38. Faulting and folding






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






40. 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






41. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






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






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






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






45. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth
