  3. What determines the physical properties of a mineral? The internal arrangement of atoms

  4. This term describes the way minerals break on irregular surfaces. Fracture

  5. What is the name of a mineral’s color in powdered form? Streak

  6. The tendency of some minerals to break along straight lines forming flat surfaces is called Cleavage

  7. What is the range of hardness values found on Mohs Hardness Scale? 1-10

  8. Name a fine grained igneous rock formed from basaltic magma Basalt

  9. An igneous rock with glassy texture, that is dark and comes from granitic lava. Obsidian

  10. Name a high density, BASALTIC, intrusive igneous rock. Gabbro

  11. DAILY DOUBLE

  12. This igneous rock is light colored, and has large grain size Granite

  13. The size of the crystals found in an igneous rock is determined by its........ Rate of cooling

  14. How are detrital sedimentary rocks classified? By particle (grain) size and shape

  15. What two processes must occur in order for loose sediment to be made into sedimentary rock? Compaction & Cementation

  16. Name the detrital sedimentary rock which is formed by angular fragments the size of pebbles or larger. Breccia

  17. In what kind of environment do rock salt, rock gypsum, and dolostone form? In a marine (ocean) environment

  18. Name a chemical sedimentary rock, that would fizz when HCl acid is added to it. Limestone

  19. In order for metamorphic rock to form, the parent rock must be subjected to..... Heat and/or Pressure

  20. Metamorphic rocks may sometimes have minerals in layers. This property is called Foliation

  21. A foliated metamorphic rock that is very shiny. Schist

  22. Which metamorphic rock shows banding? Gneiss

  23. When limestone is metamorphosed it becomes… Marble

  24. What kind of rock is produced if quartz sandstone is subjected to long periods of heat and/or pressure? Quartzite

  25. What kind of rock is produced when magma cools and solidifies underground? Intrusive Igneous

  26. Name a rock that may be produced when a sea evaporates. Rock salt

  27. What sort of rocks: igneous, sedimentary or metamorphic are most likely to form in stacks. Sedimentary

  28. What property of a rock is illustrated by the diagram? Cleavage

  29. The silicate minerals have which 2 elements in their chemical formula? Silicon and Oxygen

  30. FINAL JEOPARDY Topic: Rocks – What else? ?

  31. Is a rock an element, compound or a mixture? Mixture!
