Rock summary

 


The rock cycle is the process of the different rock types changing into the others.  The Magma comes out of the Volcano and known as Lava.  When Lava cools down and solidifies by the time, it turns into Igneous Rock.  Then by weathering the rock breaks into small pieces of rock which called sediments.  After this process sediments moves by air or water which known as erosion.  When erosion stops new rock forms called Sedimentary Rock.  Sedimentary rock forms by Compaction and Cementation.  After  Metamorphic Rock formed by heat & Pressure.  When Metamorphic rock  go deep down near Magma by heat the rock starts to melt and turns into Magma.  Rock changes to metamorphic rock by heat and pressure.  This process forms a Metamorphic rock.  The Metamorphic rock keep going down and heat melts Metamorphic rock into magma.  The rock cycle support working to different processes.
