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. 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






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






3. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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






5. There are approx. _____ days between each lunar cycle






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






7. 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






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






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






10. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti






11. 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






12. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






13. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






14. 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






15. 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






16. 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






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






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






19. 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






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






21. The degrees north or south of the equator






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






23. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






24. Forms over land and is associated with dry air






25. 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






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






27. Somewhat cooler disturbances in the photosphere






28. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






29. Bbreaking along flat surfaces






30. Human civilization has lasted only _____ years






31. Younger beds were originally deposited above older beds






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






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






34. Continental tropical (dry - warm air)






35. 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






36. One tidal cycle per day






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






38. 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






39. 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






40. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






41. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






42. 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






43. How much matter is in the object






44. 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






45. Mountains blocking the path of precipitation to the desert






46. 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
