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






2. How much matter is in the object






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






4. 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






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






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






7. 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






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






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






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






11. Weather occurs primarily due to density (temperature and moisture) differences between one location and another - These differences can occur due to the angle of the sun at any particular spot - which varies by latitude from the tropics






12. 1 hour of time






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






14. Forms over land and is associated with dry air






15. 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






16. Temperature - pressure - and composition






17. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






18. The degrees north or south of the equator






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






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






21. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






22. Form when dissolved mineral solutions crystalize out of lakes and oceans






23. The science of the atmosphere and weather






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






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






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






27. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






28. 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






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






30. Center: 3000

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






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






33. The degrees east or west of the prime meridian through Greenwich - England






34. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler

36. 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






37. Bbreaking along flat surfaces






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






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






40. 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






41. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans






42. The precipitation that is intercepted by plant foliage and eventually evaporates back to the atmosphere rather than falling to the ground






43. 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






44. 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
