Understanding the Rock Cycle:

The rock cycle illustrates how the three main types of rocks — igneous, sedimentary, and metamorphic — transform into one another through various geological processes.

Here are the key processes:

- Cooling & Hardening: Magma (molten rock) cools to form igneous rock.
- Weathering & Erosion: Rocks break down into sediments.
- Compaction and Cementation: Sediments are compacted and cemented to form sedimentary rock.
- Heat & Pressure: Can change sedimentary or igneous rocks into metamorphic rock.
- Melting: Any rock can melt into magma.
- Magma → Igneous Rock via cooling.
- Sedimentary Rock → Metamorphic Rock under heat/pressure.
- Metamorphic Rock → Magma via melting.
- Igneous Rock → Sedimentary Rock via weathering, erosion, compaction, cementation.
- Metamorphic Rock → Igneous Rock via melting and cooling.

Step-by-step Analysis of the Diagram:

Let’s label each blank based on the arrows and processes.

#### 1. Top Rectangle (from Cooling & Hardening):
- Process: Cooling & Hardening
- This comes from magma, so this box must be Igneous Rock.
✔ Top rectangle = Igneous Rock

#### 2. Right Oval (from Weathering & Erosion of Igneous Rock):
- Igneous rock undergoes weathering and erosion → becomes sediment.
✔ Right oval = Sediment

#### 3. Bottom Right Rectangle (from Compaction and Cementation of Sediment):
- Sediment → Compaction and Cementation → Sedimentary Rock
✔ Bottom right rectangle = Sedimentary Rock

#### 4. Left Oval (from Melting):
- All rocks can melt → become magma.
- The arrow labeled "Melting" points upward to this oval.
✔ Left oval = Magma

#### 5. Bottom Left Rectangle (from Heat & Pressure acting on Sedimentary Rock):
- Sedimentary rock → Heat & Pressure → Metamorphic Rock
✔ Bottom left rectangle = Metamorphic Rock

#### 6. Center Arrow (from Igneous Rock to Metamorphic Rock):
- Igneous rock → Heat & Pressure → Metamorphic Rock
- So, the arrow from Igneous Rock (top) to Metamorphic Rock (bottom left) is correct.
✔ This confirms that Metamorphic Rock is correctly placed at bottom left.

✔ Final Filled-in Diagram:

| Position | Label |
|--------|-------|
| Top Rectangle | Igneous Rock |
| Right Oval | Sediment |
| Bottom Right Rectangle | Sedimentary Rock |
| Left Oval | Magma |
| Bottom Left Rectangle | Metamorphic Rock |

🔁 Complete Rock Cycle Flow:

1. Magma → Cooling & Hardening → Igneous Rock
2. Igneous Rock → Weathering & Erosion → Sediment
3. Sediment → Compaction and Cementation → Sedimentary Rock
4. Sedimentary Rock → Heat & Pressure → Metamorphic Rock
5. Metamorphic Rock → Melting → Magma
6. Igneous Rock → Heat & Pressure → Metamorphic Rock
7. Metamorphic Rock → Weathering & Erosion → Sediment
8. Sedimentary Rock → Melting → Magma

All cycles connect and repeat!

📌 Summary Answer:

Fill in the blanks:

- Top rectangle: *Igneous Rock*
- Right oval: *Sediment*
- Bottom right rectangle: *Sedimentary Rock*
- Left oval: *Magma*
- Bottom left rectangle: *Metamorphic Rock*

This completes the rock cycle with all missing information filled in correctly.
