It starts with metamorphic rock
When a metamorphic rock is melted it turns into magma. If it is not melted then it can erode into sediments that will years latter be sedimentary rock.
This is a picture of Erosion. Erosion is when wind water or ice is broken down.
Weathering is when wind water or ice is transported from one spot to another.
This is a picture of magma from molten crust and mantel. Magma is formed when metamorphic rock is melted, or igneous rock is melted, or sedimentary rock is melted. But through volcanic activity magma can turn into igneous rock.Melting is when something gets heated up and then it becomes liquified by the heat.
This is a picture of igneous rock about to be melted.
Igneous rock is formed when magma cools. When magma cools above the Earths surface it is called Extrusive Igneous Rock. The magma that cools below the Earths surface is called Intrusive Igneous Rock. Under heat and pressure igneous rock can be turned into metamorphic rock, or if it erodes then it can turn into sediment, or if it melts then it can turn back into lava.
Sediment is formed when any type of rock erodes. When sediment depositions, or is transported, or laid down on top of other sediment then over a long period of time it turns into Sedimentary rocks.
This is a picture of sediments. If the sediments sit there for a long period of time and other sediments get on top of them then they will compact together and cement together, provided wind rain water and ice.
This is a Sedimentary rock. It has lots of little pebbles in it from compaction and cementation over lots of years. When sedimentary rocks erode then they turn into sediments again. But they can also melt to be magma, or they can be turn into metamorphic rock under heat and pressure.
This is deposition
this heat and pressure
