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. Maritime tropical (wet - warm air)






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






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






4. Used to arrange strata in a standard order - Used to measure the amount of radioactive decay in minerals and calculate the time at which the rock formed






5. One tidal cycle per day






6. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra






7. The runoff produced by melting snow






8. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






9. The science of the atmosphere and weather






10. Characterized by similar temperatures and moisture levels






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






12. Forms over the Tropics and is warm






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






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






15. Bbreaking along flat surfaces






16. Rocks are placed into groups according to how they form...






17. The tidal force produced by the sun is ____ as large as that produced by the moon






18. 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






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






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






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






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






23. 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






24. 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






25. Large - dark clouds that indicate thunderstorms






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






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






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






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






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






31. Oceans cover __ of the earth's surface






32. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

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






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






35. Occur twice a year - when the tilt of the earth's axis is oriented neither from nor to the sun - causing the sun to be located vertically above a point on the equator - The name derived from the Latin aequus (equal) and nox (night) - because at the e






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






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






38. - 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






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. This scale assigns a fixed number to 10 reference materials. Talc (1) is the softest and diamond (10) is the hardest

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






42. Featherlike clouds that indicate fair weather






43. Temperature - pressure - and composition






44. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






45. 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






46. Continental tropical (dry - warm air)






47. Seas - gulfs - bays - and other names






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






49. 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






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