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. The height of a place above sea level.






2. The areas of & in & or constituting a city.

5. A plate boundary in which plates on opposite sides of the boundary move past each other in opposite directions. The San Andreas fault of California is a good example.






6. A volcano that is composed of alternating layers of lava and pyroclastic material & along with abundant dikes and sills. Viscous & intermediate lava may flow from a central vent. Example: Mt. Fuji in Japan.

9. A commonly used measure of earthquake magnitude & based on a logarithmic scale. Each integral step on the scale represents a tenfold increase in the extent of ground shaking & as recorded on a seismograph.






10. Any porous and permeable rock that yields oil or natural gas.






11. A major drainage divide separating the drainage to one ocean from another.






12. Water beneath the Earth's surface.






13. A type of disintegration in which jointed rock is forced apart by the expansion of water as it freezes in fractures.






14. An era of geologic time lasting from 570 to 245 million years ago.






15. A geometrical form taken by a mineral & giving external expression to orderly internal atomic arrangement.






16. The process by which an unconsolidated deposit of sediments is converted in to solid rock.






17. Soil conditions prevailing in area whose mean annual temperature is 0o C.






18. The direction & north (normal) or south (reversed) & that a magnetic compass needle points.






19. Rock formed from the accumulation of sediment & Which may consist of fragments and mineral grains of varying sizes from pre-existing rocks & remains or products of animals and plants & the products of chemical action & or mixtures of these.






20. Sediments produced directly by the life processes of plants or animals.






21. Materials that are found in nature that are useful or necessary for people to live.






22. Living on land.






23. The first scientist to make systematic use of the telescope in looking at the heavens.






24. Heat transport by direct transfer of energy from one particle to another & without moving the particle to a new location.






25. Living parts of the environment that can renew or replace themselves.






26. The southern portion of the late Paleozoic supercontinent known as Pangea. It means & literally 'Land of the Gonds' (a people of the Indian subcontinent).The supercontinent existed from Cambrian to Jurassic time & mainly composed of South America &






27. Heat transport by direct transfer of energy from one particle to another & without moving the particle to a new location.






28. A wall built out from the shore & usually at perpendicular to it to trap sand carried by longshore currents .






29. Where one plate slides beneath another plate as the two are pushed together & a subduction zone.






30. The process by which an unconsolidated deposit of sediments is converted in to solid rock.






31. Saturn is named after the Roman god of the harvest. It is the sixth planet from the Sun.






32. A vent in the surface of the Earth & from which lava & ash & and gases erupt.






33. The process by which ocean floors spread laterally from crests of main ocean ridges. As material moves laterally from the ridge & new material replaces it along the ridge crest by welling upward from the mantle.






34. An abandoned meander .






35. Imaginary lines on a map or globe that measure distance in degrees east or west of the prime meridian. Longitude lines extend vertically & from pole to pole on a globe.






36. The persistence of wind-formed waves after wind ceases.






37. The concept of a sequence of events involving the formation & alteration & destruction and reformation of rocks as a result of geologic processes.






38. A measure of the strength of an earthquake based on the amount of movement recorded by a seismograph . compare Richter scale.






39. (Latin- Sol & Greek- Helios)the closest star to Earth. It is a giant ball of gas without any solid surface.






40. The area immediately below the ground surface within which pore spaces are partially filled with water and partially filled with air.






41. The distance between two successive wave crests or troughs.






42. The galaxy where Earth is located.






43. Large area of extremely flat ocean floor lying near a continent and generally over 4 km in depth.






44. An area in which a large number of windmills have been erected to generate electrical power.






45. Where two plates are moving in opposite directions as in a mid-ocean ridge.






46. The theory that states that the present-day continents are the fragmented pieces of preexisting larger landmasses called supercontinents.






47. The primary division of geologic time which are & from oldest to youngest & the Hadean & Archean & Proterozoic & and Phanerozoic eons.






48. A layer of sedimentary rock; plural is strata.






49. 1. Breach in a natural levee . 2. Deep crevice or open fracture in glacier ice.






50. 1. A mass of sand & gravel & or alluvium deposited on the bed of a stream & sea & or lake & or at the mouth of a stream 2. A unit of pressure & approximately equal to atmospheric pressure at sea level.
