Answer:
2. The heat and pressure act on the sedimentary rock causing the transformation into metamorphic rock.
4. The magma is released at a high temperature, but eventually cools, forming the igneous rock.
Step-by-step explanation:
As requested, the two sentences presented above show the steps that were missing in the process of transforming sedimentary rock into metamorphic rock and the formation of igneous rock, which is a magmatic rock, since it depends entirely on the solidification of terrestrial magma to be composed. Metamorphic rocks, in turn, are modifications of the original rocks.
