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. A term applied to large areas of basaltic lava presumably extruded from fissures.






2. A stone or boulder & glacially transported from place of origin and left in an area of different bedrock composition.






3. (Latin- Terra & Greek- Gaia) Earth is named after the ancient Germanic Goddess of the soil. It is the third planet from the Sun.






4. An era of time during the Phanerozoic eon lasting from 245 million years ago to 66.4 million ago.






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






6. A flood that rises and falls very rapidly.






7. A large area with common features that set it apart from other areas.






8. 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.

17. The straightening and/or deepening of a river channel.






18. The chronological sequence of units of Earth time.






19. That portion of the resources for a valuable mineral commodity that can be extracted from the Earth at a profit today.






20. In the geologic time scale a unit of time less than an era and greater than an epoch. Example: The Tertiary period was the earliest period in the Cenozoic era and included & among others & the Eocene epoch.






21. Surficial mining & in which the valuable rock is exposed by removal of overlying rock or soil.






22. The perpendicular or very steep descent of a stream.






23. An icicle-shaped accumulation of dripstone hanging from cave roof.






24. A river that is able to maintain its flow through a desert because of water received from outside the desert.






25. A tool for measuring the relative clarity of water.






26. Weathering processes that are the result of chemical reactions. Example: the transformation of orthoclase to kaolinite.






27. An instrument used to measure the speed of wind.






28. Plutonic. Antonym of extrusive. Pertaining to igneous rocks or features formed by the emplacement of magma in pre-existing rocks.






29. The two days of the year on which the noon sun is directly overhead at either 23.5
