  11. Definite crystalline shape

  20. ROCK Made up of 2 or more minerals

  21. IGNEOUS ROCK http://mineral.galleries.com/rocks/igneous.htm

  22. IGNEOUS ROCK

  23. SEDIMENTARY ROCK

  24. METAMORPHIC ROCK

  25. Which type of rock would have formed first on the original crust? • Igneous

  26. Examples: sand silt clay Examples: sandstone Shale limestone SEDIMENTARY ROCK Lithification (compaction & cementation) Sediments High Temperature High Pressure Weathering Erosion METAMORPHIC ROCK IGNEOUS ROCK Melting Examples: granite basalt pumice Examples: slate marble gniess quartzite Magma Cooling Crystallization

  27. ROCK CYCLE http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html

  28. In your own words, describe how each type of rock could turn into each of the other types of rock.

  29. shells deposition calcite lithification limestone High heat & pressure marble

  30. sand deposition silicate lithification sandstone High heat & pressure quartzite

  31. clay silt deposition silicate lithification shale High heat & pressure slate

  32. magma Cooling & Crystallization Mineral grains aligned in thick layers (foliation); less than 50% Granite High heat & pressure gneiss

  33. EXTRUSIVE (cools quickly) magma Cooling & Crystallization heat & pressure basalt green stone Cooling & Crystallization More heat & pressure Green schist Granite INTRUSIVE (cools slowly) High heat & pressure schist Mineral grains aligned into thin layers (foliation); 50% or more
