Question

the diagram below is a model of the rock cycle. the diagram shows how one type of rock can change into another type of rock.
select the magma.

Explanation:

In the rock cycle diagram, magma is represented by the box with the volcano - like (lava - related) icon at the bottom. This is because magma is the molten material that can crystallize to form igneous rocks, and the arrows like "melting" from other rock types point towards it, and "crystallization" points away from it (indicating it cools to form rocks), which matches the definition and role of magma in the rock cycle.

Answer:

The box at the bottom of the diagram with the volcano - like (molten - looking) icon (the one with the orange - colored molten material illustration) represents magma.
