What should a model of the rock cycle show as the process that changes metamorphic rock to igneous rock?(1 point)

heating followed by pressure

weathering followed by erosion

compaction followed by cementation

melting followed by cooling

melting followed by cooling

The process that changes metamorphic rock to igneous rock involves melting followed by cooling.

To determine which process changes metamorphic rock to igneous rock, we need to understand the rock cycle. The rock cycle is a continuous process where rocks are transformed from one type to another over time. Here's how you can go about finding the answer:

1. Start by understanding the different processes involved in the rock cycle. The three main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form when molten magma or lava cools and solidifies. Sedimentary rocks are formed from the accumulation and consolidation of sediments. Metamorphic rocks are created from existing rocks that undergo changes due to high pressure and temperature.

2. Analyze the options provided and determine which process is involved in transforming metamorphic rock to igneous rock.

- Heating followed by pressure: This process describes the formation of metamorphic rocks, not the transformation into igneous rocks.

- Weathering followed by erosion: This process describes the breakdown and transport of rocks, not the transformation of one rock type to another.

- Compaction followed by cementation: This process describes the formation of sedimentary rocks, not the transformation into igneous rocks.

- Melting followed by cooling: This process is associated with the formation of igneous rocks, specifically, when magma or lava cools and solidifies.

3. Based on the analysis, the correct process that changes metamorphic rock to igneous rock is "melting followed by cooling."

Therefore, a model of the rock cycle should show that metamorphic rock is transformed into igneous rock through the process of melting followed by cooling.
