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.

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






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






6. 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






7. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






8. 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






9. Maritime polar (wet - cold air)






10. 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






11. 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






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






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






14. Refers to the long - term weather patterns of a large geographical area and takes into account temperature - humidity - and precipitation






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






16. Cirrus - Stratus - Cumulonimbus - Altostratus






17. The degrees north or south of the equator






18. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






19. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






20. Characterized by similar temperatures and moisture levels






21. Affected by factors such as weathering and impurities






22. Somewhat cooler disturbances in the photosphere






23. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






24. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






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






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






27. A major determiner of coastal climate






28. Piled in waves and indicate rain or snow






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






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






31. 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






32. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






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






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






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






36. Featherlike clouds that indicate fair weather






37. Continental polar (dry - cold air)






38. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






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






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






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






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






43. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






44. 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






45. Forms south of the Arctic and is cold






46. Forms over water and is associated with wet air






47. Formed by sodium chloride






48. The strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






49. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment






50. 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
