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.

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






2. 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






3. Some groundwater finds openings in the land surface and emerges as...






4. 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






5. Mountains blocking the path of precipitation to the desert






6. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






7. 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






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. Water transpired from plants and evaporated from the soil






10. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






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






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






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






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






15. 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






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






17. Seas - gulfs - bays - and other names






18. Form when dissolved mineral solutions crystalize out of lakes and oceans






19. Human civilization has lasted only _____ years






20. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






21. Bbreaking along flat surfaces






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






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






24. Texture is important in classifying ______ sedimentary rocks






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






26. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






27. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






28. 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






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






30. Large - dark clouds that indicate thunderstorms






31. Piled in waves and indicate rain or snow






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






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






34. Formed by sodium chloride






35. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






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






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






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






39. The outermost part of the earth's interior is made up of two layers...






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






41. 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)






42. 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






43. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






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






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






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






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






48. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






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






50. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes
