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. 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






2. 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...






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






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






5. 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






6. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






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






8. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






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






10. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






11. Maritime polar (wet - cold air)






12. 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






13. 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






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






15. Some groundwater finds openings in the land surface and emerges as...






16. Affected by factors such as weathering and impurities






17. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






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






19. Characterized by similar temperatures and moisture levels






20. 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






21. The resulting dust layer would act as a shield - blocking out much of the sun's rays - This would result in lower global temperatures and a general _____ of the earth






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






23. This upslope wind is called a...






24. The process in which one type of rock changes into another






25. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






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






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






28. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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






30. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






31. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






32. Faulting and folding






33. Maritime tropical (wet - warm air)






34. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






35. 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)






36. Bbreaking along flat surfaces






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






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






39. 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






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






41. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






42. Mountains blocking the path of precipitation to the desert






43. Water transpired from plants and evaporated from the soil






44. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






45. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






46. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






47. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans
