Does a rock go through the complete rock cycle by changing from igneous rock to sedimentary to metamorphic?

Yes, a rock can go through the complete rock cycle by starting as an igneous rock, then transforming into sedimentary rock through weathering and erosion, and finally becoming metamorphic rock through heat and pressure. This cycle can repeat due to Earth's constant processes.


Is breccia a sedimentary metamorphic or igneous rock?

Yes. In the rock cycle, any sedimentary rock can be transformed into a metamorphic rock due to deep burial where the rock is changed by the earth's high temperature and pressure, an exposure to a plutonic intrusion, where rocks such as granite are formed, or any other process where heat and pressure alter the composition, appearance, and classification of a rock. An igneous rock can turn into a metamorphic rock or a sedimentary rock. A metamorphic rock can turn into an igneous rock or a sedimentary rock, and a sedimentary rock can turn into an igneous rock or a metamorphic rock.
