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






2. A continuous drill would find gas - oil - and water in that order - The three substances occur in their order of density - with the lightest substance on top and the heaviest on the bottom






3. 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






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






5. Water transpired from plants and evaporated from the soil






6. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






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






8. 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






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






10. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






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






12. Volcanoes are generally found where ________ are diverging or converging






13. 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






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






15. Continental tropical (dry - warm air)






16. Affected by factors such as weathering and impurities






17. 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






18. 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






19. 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)






20. Temperature - pressure - and composition






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






22. - 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






23. Defined by geometrically subdividing the earth's spheroid into 24 lunes (wedge - shaped sections) - bordered by meridians - each 15






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






25. Forms over the Tropics and is warm






26. Faulting and folding






27. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






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






29. 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)






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. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip






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






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






34. 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






35. 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






36. Oceans cover __ of the earth's surface






37. Characterized by similar temperatures and moisture levels






38. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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






40. How much matter is in the object






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






42. Seas - gulfs - bays - and other names






43. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






44. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






45. Piled in waves and indicate rain or snow






46. 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






47. Runoff and groundwater are stored as ________ in lakes






48. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






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