Rock Types

  Rock cycle is the model that descirbe how sedimentary rock, metamorphic rock, and Igneous rock slowly change from one th another throught time. Igneous are made by magma or lava turning solid by a cool temperature. When Igneous rock break down into small pieces by wind and water that makes sediments. When sediments go to a new place, compaction (push together) and cementation (glue together), that make sedimentary rock., When heat and pressure push sedimentary rock, it becomes metamorphic. If metamorphic rock melt, it will become magma or lava.

Rock
Metamorphic rock- underground by heat and pressure

Magma- melted rock inside earth

Solidification- get cold, liquid to solid

Igenous rock- cooling crystallization of magma

Weathering- break rock into small pieces by wind and water

Erosin- replaced to a new place

Sediment- broken pieces of rock

Compaction- stick together and form solid rock

Cementation- glued together

Sedimentary rock- pieces of sediments combine

Rock Types

       Igneous rock

Extrusive Igneous- have small crystal, and from outside of volcano

Intrusive Igneous- have big crystal, and from inside of volcano





   Sedimentary rock

Clastic- just a rock

Bioclastic-  have death organism on it

Crystalline- rock form from liquid



 Metamorphic rock

 


Non-foliated- don't have layer

Foliated- have layer

Crystals & Minerals

Crystals
   In Crystal Growth Lab, we made a solution by mix the mineral, then replaced this solution to the window,  to let them grow the crystal by the 10 days.  In each day, we need to measured the crystal, and to observed the crystal, like: color, shape. That help us to see how they growth, and wrote down into the data.

Mineral Properties
  Color - a color other than white or clear

 Luster - metallic: look like metal                      

  Non metallic: does not look like metal

Streak - scratch the mineral on the streak plate

  Hardness- soft and hard

 Cleavage- break evenly                         








Fracture- break unevenly

Mineral Identification                            

Sulfur 


 * Nonmetallic luster
 * White- yellow streak
 *  Yellow to amber
 * Soft (2)
 * Fracture

 Pyrite

 * Metallic luster
 * Green- black streak
 * Brassy Yellow
 * Hard (6.5)
 * Fracture
