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
