The Rock Cycle
The rock cycle is a process that slowly changes rocks into another kind of rock than what it already was. That takes place on the earth's surface and in it's crust and mantle.
How the Rock Cycle works
It works like a clock it keeps going round and round like a clock. It starts with one kind of rock and then keeps changing into another kind of rock. It starts with Igneous rock can transform to sediment from erosion/melting causing it to magma and lava.
Sediment can become sedimentary rock from deposition.
Sedimentary rock becomes metamorphic rock from heat and pressure or goes through erosion to become sediment. Also can go through melting and become magma and lava.
Metamorphic rock can transform into magma and lava by melting or erosion can happen and transforms into sediment.
Magma and Lava can become igneous rock by going through volcanic activity.
Sediment can become sedimentary rock from deposition.
Sedimentary rock becomes metamorphic rock from heat and pressure or goes through erosion to become sediment. Also can go through melting and become magma and lava.
Metamorphic rock can transform into magma and lava by melting or erosion can happen and transforms into sediment.
Magma and Lava can become igneous rock by going through volcanic activity.
Plate Tectonics
Plate Tectonics are the process that help start the Rock Cycle by rubbing the plates together so it starts the Rock Cycle.
