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
