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. 1 hour of time






2. Characterized by similar temperatures and moisture levels






3. 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






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






5. Maritime polar (wet - cold air)






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






7. Water transpired from plants and evaporated from the soil






8. 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






9. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






10. 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






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






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






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






14. Human civilization has lasted only _____ years






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






16. Cirrus - Stratus - Cumulonimbus - Altostratus






17. 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






18. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






19. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






20. Somewhat cooler disturbances in the photosphere






21. 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






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






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






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






25. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






26. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






27. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






28. Large - dark clouds that indicate thunderstorms






29. 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






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






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






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






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






34. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






35. Sometimes called minor planets or planetoids - Bodies






36. Continental tropical (dry - warm air)






37. 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






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






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






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






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






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






43. 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






44. 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






45. 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






46. 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






47. How much matter is in the object






48. 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






49. Forms over land and is associated with dry air






50. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...
