In the rock cycle, the type of rock that occurs in the part labeled B would depend on the specific process happening at that stage. However, without additional context about what stage B represents, I can provide a general guide:
- Metamorphic rocks form from the transformation of existing rocks under heat and pressure.
- Igneous rocks form from the cooling and solidification of magma or lava.
- Sedimentary rocks form from the accumulation and compaction of sediments.
If B represents the process where existing rocks are transformed due to heat and pressure, it would be metamorphic. If it signifies cooling magma, it would be igneous. If it indicates the accumulation of sediments, it would be sedimentary.
Based on a common understanding of the rock cycle, if it involves heat and pressure, the answer would be metamorphic. If that is not the context for B, please clarify the specific process for more precise help.
