Video of Rock Cycle !


Rock Cycle - Class M - #4 from Kara MacDevitt on Vimeo.
Sedimentary: rocks formed by cementation and compaction

















Rock Types 
Igneous Intrusive: rocks inside the volcano with big crystals















Igneous Extrusive: rocks outside the volcano with small crystals















Sedimentary Clastic: broken pieces of old rocks















Sedimentary Crystalline: liquid evaporates and formed crystal

















Sedimentary Bioclastic: dead animals














Metamorphic Foliated: rocks have lines















Metamorphic Non-Foliated: rocks doesn't have lines

Rocks
Cementation: when layers get together




Sedimentary Rock : rock formed by differents types of sediments

 




Rock Types

Igneous Intrusive: formed inside volcano, small crystal





Rock Cycle

The rock cycle is a process in which three type of rocks change one to another. By different process. 
The magma melted inside the volcano than lava cools off. Then formed a solid rock called Igneous rock. Weathering moves by water, ice, and sand form a sediment rock. They burial together and compacted in three layers. Than cemented and formed a Sedimentary rock. They get hitted by heat and pressure.That change them into a Metamorphic Rock. Than melted back into the magma.


Rocks

Metamorphic rock: rock formed by heat and pressure.



Magma: middle of earth

 


 
Lava: liquid coming out the volcano



Solidification: when magma turns into a solid piece



 




Igneous Rock: rock formed when lava cools off





 






Weathering: broking pieces of rock
 




Erosion: move to another place by water and wind









 










 








Compaction: layers top bottom middle of sediments

Crystals and minerals
Streak: powder left by the minerals




Hardness: how hard and soft is the mineral


Cleavage: when mineral is cut even


 
Fracture: when mineral is cut uneven
 
 
Other properties such as: magnetic, smooth, rough, dark, sparkle, shiny, opaque, clear, light, heavy.






 
 
 










Crystals and minerals
Luster:


Metallic: look like a mineral


Non-metallic: doesn't look like a mineral
 
Color: what the mineral look like

Cleavage


















 Graphite

Color: silver to gray
uses for pencil lead and lubricants
Fracture
 Hardness:1-2
