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
