The process that would change metamorphic rock to igneous rock is melting followed by cooling.
The process that would change metamorphic rock to igneous rock is melting followed by cooling. Here's how you can understand why:
1. Metamorphic rock forms when existing rocks are subjected to intense heat and pressure, causing them to change in composition and structure.
2. Igneous rock, on the other hand, forms from the cooling and solidification of molten material, usually magma or lava.
Now, let's break down the options provided and see which one aligns with this concept:
- Erosion followed by compaction: This process refers to the gradual wearing away of rocks and their subsequent compression. It does not involve the transformation of metamorphic rock into igneous rock.
- Pressure followed by weathering: Pressure is indeed involved in the formation of metamorphic rock, but weathering typically occurs after rocks have been exposed to the surface and breaks them down. This process does not lead to the formation of igneous rock either.
- Cooling followed by cementation: Cementation is a process that occurs during the formation of sedimentary rocks, involving the binding together of loose particles. It does not apply to the transformation from metamorphic to igneous rock.
Hence, the correct answer is "melting followed by cooling." When metamorphic rock melts due to extreme heat and turns into molten material (magma), it can eventually cool and solidify to form igneous rock.
