Crystals & Minerals

Crystals gorwth
We learned that crystal growth in science class, we were learned two types of crystals. We created a solution by mixing minerals with water. We are get a pencil and tied the string in the middle.We put amount of minerals in a beaker with some water, when the water going heat that we put amount of minerals into the beaker and used tool to mixing it with the water.Finally, we put the beaker next the window and waiting it is cooling.The result is minerals becomes crystal. We were doing same thing with another minerals. We learn temperture affect the crystals growth.


Mineral properties
Luster
metallic- the minerals look like the metal
 nonmetallic - does not look like metal
 
 color -  the surface color of rocks
 streak - the color of minerals that streak in the streak plate
 hardness- a measure soft or hard of rock
cleavage- break of rock in evenly
 fracture- break of rock in unevenly
 composition- some mineral made uo to a  mineral

Mineral Identification
    Sulfur
Luster: nonmetallic
Hardness: 2
It is fracture
Color: yellow
Composition: S


luster: metallic
hardness: 6.5
it is break fracture
color: brassy yellow
composition: FeS2

rock cycle

ROCK CYCLE
       The rock cycle is natural processes of rock change from different kinds of rock. The magma move up through the volcano change to the lava get cooling become the Igneous rock. The Igneous rock was through the weathering and erosion become the sediments. The sediments are compaction,then they glue all thing together become sedimentary rock. The sedimentary rock get heat and pressure becomes the metamorphic rock. The Mentamorphic rock through solid to liquid by heat to the lava. The rock cycle never stop.


ROCKS


Metamorphic rock - rock by heat or pressure
 

Magma- melting rock inside the earth

 Solidification- to become solid,very heat

Igneous rock- rocks that from when magma become cool and solid.
 
 Weathering process of breaking rocks into small peaces.
 Erosion- process of when materials are moved by weather

 Sediment- rock peaces

 Compaction- process of when the piece of rock getting together.

 Cementation- process when the piece of rock glue each other

 Sedimentary rock- from by another piece of rock running by water getting each other



ROCK TYPES
Sedimentary rock
Clatic - from by broken piece of rock and running with water meet with other piece of rock then stick together

 Crystalline - from by chemical make up

 Bioclastic - form in same way with clastic but it consisting with dead animals

 Igneous rock
Intrusive inside of volano make big crystals
 Extrusive - outside of volano make small ctystal

 Metamorphic rock
Foliatedoutside of a metamorphic rock has a line

 Non-Foliated - ouside of a metamorphic rock does not have a line
