The Rock Cycle
The rock cycle is the process in which rocks are formed and then changed from one type of rock to another. The three main types of rocks are igneous, metamorphic, and sedimentary rock. All of these rocks can be changed by cementing, compacting, cooling, melting, heating, erosion, and/or being pressurized. Rocks are not the only part of the cycle though because sediment and magma can also become rock!

How It Works
the magma is held in the magma chamber then it is lifted out and above the surface. The lava (magma) then cools in a process called crystallization and turns into igneous rock. The rock is then weathered by rain and the sediment that comes off of the rock erodes down into bodies of water. The sediment then enters a process called lithification (compaction & Cementation)were its is turned into sedimentary rock. The rock is then pushed down into the earth and it is morphed into metamorphic rock! The metamorphic rock is then pushed even further down into the earth and melts into Magma... The Cycle Restarts...
