Rock Types

Rock Cycle:
Magma/Lava goes outside of the volcano, lava becomes into igneous rock by cooling. Because the weathering and erosion, the rock is broke down into small pieces called sediments. The sediments are deposited at specific place,which are moved by erosion, the sediments start to be squeezed, are compacted and holding together, cementation. The sediments become into sedimentary rocks. The sedimentary rock becomes into metamorphic rocks, because the heat and the pressure. Finally, because the high heat, metamorphic rock becomes  into magma, goes inside of the volcano, and the cycle begin again.


Rock Types:


Metamorphic Rock - A rock from other existent by the process called metamorphism.
Magma/ Lava - Hot liquid rock inside of the volcano/ hot liquid outside of the volcano.
Solidification- The process of cooling.
Igneous Rock - A rock formed by solidification of magma/lava.
Weathering - Process by the rock breaks down into small pieces.
Erosion - Process by the sediments are transported.
Sediments - Small pieces from existent rocks.
Compaction - Process by the sediments are squeezed.
Cementation - Process by the sediments hold together, like glue.
Sedimentary Rock - Rock formed by sediments, that are deposited by lies.

Igneous Rock 

Intrusive - Rock solidifies slowly within the crust of a planet.




Extrusive - Rocks formed at the crust surface as a result of melting of rocks within the mantle and crust.



Sedimentary Rocks

Clastic - Rock formed by small piece of existent rocks.



Crystalline - Rock formed by the precipitacion of minerals from a water solution. 


Bioclastic - Rock formed by rest of animal or plants death.


Metamorphic Rocks

Foliated - Rock which is arranged  by layers.



Non - Foliated - Rock which is not arranged by layers.
