1. Melting and Crystallization: If a metamorphic rock is subjected to even higher temperatures and pressures, it can melt into magma. This magma, when it cools and solidifies, will form igneous rocks. This process is known as the igneous cycle.
2. Erosion and Deposition: Over time, metamorphic rocks can be exposed to weathering and erosion, breaking them down into smaller fragments. These fragments can be transported by wind, water, or ice, and eventually deposited in a new location. These sediments can then be buried and compacted, potentially forming sedimentary rocks through the process of lithification.
