IXL | Label parts of rock cycle diagrams | 6th grade science - Free Printable

Let’s solve this step by step using the rock cycle diagram and the hint.

We are given 5 labels to place:
- metamorphic rock
- sedimentary rock
- igneous rock
- sediment
- magma

And we have a hint:
> During crystallization, liquid rock cools and hardens to form solid rock.

That means when something is labeled “crystallization,” it turns into igneous rock (because that’s how igneous rocks form — from cooling magma or lava).

Now let’s look at the arrows in the diagram:

1. The arrow labeled “melting” points to a red/orange area deep underground → that must be magma (molten rock).
2. From magma, an arrow goes up labeled “crystallization” → that forms igneous rock.
3. Igneous rock on the surface gets broken down by “weathering and erosion” → that makes sediment.
4. Sediment gets buried and turned into rock by “compaction and cementation” → that makes sedimentary rock.
5. Sedimentary rock (or any rock) under heat and pressure becomes metamorphic rock via “heat and pressure”.
6. Metamorphic rock can melt back into magma.

So now let’s match each blank box based on where the arrows point:

Top left box → points to material formed after weathering and erosion → that’s sediment

Top right box → points to rock formed after compaction and cementation → that’s sedimentary rock

Middle right box → points to rock formed from crystallization of magma → that’s igneous rock

Bottom left box → points to molten material that melts from other rocks → that’s magma

Bottom right box → points to rock formed from heat and pressure → that’s metamorphic rock

Let’s double-check:

- Magma → crystallizes → igneous rock ✔
- Igneous rock → weathered → sediment ✔
- Sediment → compacted → sedimentary rock ✔
- Sedimentary rock → heated/pressured → metamorphic rock ✔
- Metamorphic rock → melted → magma ✔

Perfect loop!

Final Answer:
Top left: sediment
Top right: sedimentary rock
Middle right: igneous rock
Bottom left: magma
Bottom right: metamorphic rock
