This metamorphic rock can be changed into a sedimentary or a igneous rock or back into another metamorphic rock by being broke into little pieces ( sediment) or by being melted into magma.
This time the metamorphic rock was melted into magma and then erupted. Then it cooled and solidified to become an igneous rock. This igneous rock is called basalt. It could also turn into a sedimentary or another metamorphic rock.
The igneous rock can be changed back to a metamorphic rock by extreme heat and pressure.
The metamorphic rock has broke into sediments and has been compacted and cemented together to become a sedimentary rock.
