what process is most likely occurring at point 9 in the diagram?\nmelting of metamorphic rock into…

Brief Explanations:

In the rock - cycle, magma cools and solidifies through crystallization to form igneous rock. At point 9, the image shows a transition from a molten state (magma) to a solid rock state. Metamorphic rock forms from pre - existing rock under high pressure and temperature, not directly from magma crystallization. Sedimentary rock forms from the accumulation and compaction of sediments. Melting of metamorphic or sedimentary rock into magma is a different process from what is depicted at point 9.

Answer:

crystallization of magma into igneous rock
