Rock Types

                                         Rock Types

Igneous Rock-Intrusive/Extrusive              
                Interusive- Igneous Rocks form inside of the volcano and has a big crystals.

       Extructive- Igneous Rocks form outside of the volcano and has a small crystals

 

 
Sedimentary Rocks-Clastic/Crystalline/Bioclastic
                 Clastic-Broken pieces of rock
                                    

                           Crystalline-Evaporation of liquid（under water).

             Bioclastic-Made from dead or ganisms(coal）
                                            

Metamorphic Rocks-Foliated/Non-Foliated
                       Foliated-The rocks have parallel bands

Non-folited-The rock have no parallel bands

Vocabulary

Magma- Melted rock inside the earth.

Lava-Melted rock outside the earth.

Igneous Rock-cooling crystallization of magma.

Weathering and Erosion-Breaking down rocks wind.

Sediments-Broken pieces of rock.

Compaction- Push together.

Cementation- Glued together.

Sedimertary Rock-Pieces of sediment comloine.

Heat and pressure-Push together

 Metamorphic Rock-underground by heat and pressure.

Summary

Sedimentary rock heat and pressure to metamorphic rock.

Metamorphic rock melting into magma.

Magma cooling down and turns into Igneous rock.

Igneous rock weathering and deposition into sediment.

Sediment change into sedimentary rock by compaction and cementation.

 The sediment rock heat and prussure into Metamorphic rock.

                                       

Crystals & Minerals

                     Crystals & Minerals 
Crystals- In Crystals grow table, we made water be come hot first, that we mixing of the Minerals of the water, one spoon at a time. when the Minerals can not melting, hat we waited the Minerals become grow.  The Minerals become Crystals. The color of the crystal was white. The luster of the crystal was non-metallic because it didn't looks like metal. The Rocks are make up of mineral.

 Minerals 
  Luster:
                 Metallic is looks like metal

     
           Non-metallic is does not look like metal

   Streak:
                     Color is a color other than white or clear

                 Colorless is white color or clear

   Hardness:
                Soft is does not scratch a glass plate(5.5)   

                 Hard is scratch the glass plate(5.5)

                                         
     Cleavage/Fracture:
                         Cleavage is after break, it is evenly.

                          Fracture is after break, it is unevenly.

                                           
     3. Mineral Identification                                   
                                         

Luster: Non- metallic
Color: Colorless/ white
Hardness: 3
Cleavage
                                         
 luster-  metal
Color- black to silver
hardness 5.5 to6.5
