If you don't know already we are talking about the rock cycle and today we will start off with the Igneous rock. The way it is created is by weathering and erosion.The rest is at the bottom.
The next rock we will be talking about from the rock cycle is the Sedimentary rock.The sedimentary rock and how it is formed is at the bottom.
The last rock is the metamorphic rock.The way it is made is by heat and/or pressure . The metamorphic rock is made after the sedimentary rock, and to become the metamorphic rock the sedimentary rock must go through metamorphism.
