  1. Chapter 2 Rock Box Review • Go through this Power Point at home to help review the different rocks and their characteristics. (It’s a way to study without the box of rocks!!) • Remember: Your Chapter 2 Test is a walk-around station test!

  2. Name the rock and its type.What characteristics do you see?

  3. Conglomerate • Sedimentary • Clastic • Large pebbles • Coarse-grained

  4. Breccia • Sedimentary • Clastic • Coarse-grained • Smaller pebbles than conglomerate

  5. Obsidian • Igneous • Extrusive • Glasslike • No visible crystals • Volcanic

  6. Shale • Sedimentary • Clastic • Fine grained • Grey

  7. Slate • Metamorphic • Foliated • Dark grey/black • Thin • Layers on side • Formed from shale with heat & pressure

  8. Sandstone • Sedimentary • Clastic • Fine grained • Crumbly / sandy

  9. Granite • Igneous • Intrusive • Big, visible crystals • Coarse grained • Black, white, and pink minerals

  10. Gneiss • Metamorphic • Foliated • Coarse grained • Flattened crystals • Evidence of pressure

  11. Schist • Metamorphic • Foliated • Flattened crystals - layers • Glittery

  12. Marble • Metamorphic • Non-foliated • White or pink • Coarse Grained (large crystals) • Evidence of pressure

  13. Quartzite • Metamorphic • Non-foliated • Light in color • Not as “sparkly/crystally” as marble

  14. Pumice • Igneous • Extrusive • Gas bubbles from cooling lava • Has holes • Very light-weight

  16. Gabbro • Igneous • Intrusive • Coarse-grained • Chunky crystals • Black

  17. Basalt • Igneous • Extrusive • Fine-grained • Black/ dark grey • Most of the ocean floor is basalt

  18. Rhyolite • Igneous • Extrusive • Fine-Grained • Lava cools quickly • Lighter in color

  19. Limestone • Sedimentary • Organic (if you see fossils) • Chemical (it formed from a solution) • Dull • Tan/light brown/gray • Fine-grained

  20. Good Luck!!  • Sources • http://skywalker.cochise.edu/wellerr/rocks/mtrx/gneissL.htm • Geologu.com
