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. 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)






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






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






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






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






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






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


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






9. 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






10. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run






11. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






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






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






14. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






15. This upslope wind is called a...






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






17. Cirrus - Stratus - Cumulonimbus - Altostratus






18. 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






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






20. Formed by sodium chloride






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






22. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






23. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






24. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






25. Younger beds were originally deposited above older beds






26. Featherlike clouds that indicate fair weather






27. 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






28. 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






29. Nearest galaxy - about 20 million light - years away






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






31. Maritime tropical (wet - warm air)






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






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






34. - 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






35. Two high waters and two low waters each day - in most locations - tides are semidiurnal






36. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






37. Form when magma or lava cools and solidifies - Depending on the rate of cooling - can contain visible crystals - while others can appear glassy






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






39. 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






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






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






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






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






44. Water transpired from plants and evaporated from the soil






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






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