🔍 Understanding the Rock Cycle

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

Here are the key processes:
- Weathering: Breaks down rocks at the surface.
- Erosion & Transport: Moves weathered material.
- Deposition of sediments: Sediments settle in layers.
- Burial & Compaction: Layers are pressed together to form sedimentary rock.
- Metamorphism: Existing rocks change under heat/pressure.
- Melting: Rocks turn into magma.
- Crystallisation of magma: Magma cools and solidifies into igneous rock.
- Uplift: Rocks are pushed upward to the surface.

✔ Step-by-step Labeling (based on typical rock cycle diagrams):

We’ll go around the cycle, starting from igneous rock formation:

#### 1. Crystallisation of magma → Igneous rock
- Magma cools and solidifies → forms igneous rock.
- So, the box next to "Crystallisation of magma" should be labeled Igneous rock.

#### 2. Weathering → Erosion & transport
- Already labeled: Weathering breaks down igneous rock.
- Then Erosion & transport moves the broken pieces.

#### 3. Deposition of sediments
- After erosion, sediments are deposited (e.g., in rivers, lakes, oceans).
- This is already labeled correctly.

#### 4. Burial & compaction → Sedimentary rock
- Sediments get buried and compacted → form sedimentary rock.
- So, the box after “Burial & compaction” is Sedimentary rock.

#### 5. Metamorphism → Metamorphic rock
- If sedimentary or igneous rock is subjected to heat and pressure, it becomes metamorphic rock.
- The process is Metamorphism, and the result is Metamorphic rock.

#### 6. Melting → Magma
- If metamorphic or any rock is heated enough, it melts into magma.
- So, the arrow leading to magma is Melting.

#### 7. Uplift
- Rocks deep underground can be pushed up to the surface via tectonic forces.
- This brings rocks back to the surface for weathering.
- The box pointing upward from deep layers should be Uplift.

📌 Final Labels (in order):

| Box Location | Correct Label |
|-------------|----------------|
| Below "Crystallisation of magma" | Igneous rock |
| After "Weathering" | Erosion & transport |
| After "Erosion & transport" | Deposition of sediments |
| After "Deposition of sediments" | Burial & compaction |
| After "Burial & compaction" | Sedimentary rock |
| After "Sedimentary rock" | Metamorphism |
| After "Metamorphism" | Metamorphic rock |
| From "Metamorphic rock" to magma | Melting |
| From deep crust to surface | Uplift |

✔ Summary of Answers:

Fill in the blanks as follows:

1. Igneous rock – below "Crystallisation of magma"
2. Erosion & transport – after "Weathering"
3. Deposition of sediments – after "Erosion & transport"
4. Burial & compaction – after "Deposition of sediments"
5. Sedimentary rock – after "Burial & compaction"
6. Metamorphism – after "Sedimentary rock"
7. Metamorphic rock – after "Metamorphism"
8. Melting – from metamorphic rock to magma
9. Uplift – arrow going upward from deep crust

> 💡 Tip: You may also see "Metamorphism" used for both the process and the resulting rock type — but in this case, the word bank includes both "Metamorphism" (process) and "Metamorphic rock" (product), so use them appropriately.

🎯 Final Answer (Labeling the Diagram):

| Position in Diagram | Label |
|---------------------|-------|
| Top-right box (after weathering) | Erosion & transport |
| Next box (after erosion) | Deposition of sediments |
| Box below that | Burial & compaction |
| Box after burial | Sedimentary rock |
| Box above sedimentary rock | Metamorphism |
| Box after metamorphism | Metamorphic rock |
| Arrow from metamorphic rock to magma | Melting |
| Box beside magma | Crystallisation of magma |
| Box below crystallisation | Igneous rock |
| Arrow from deep crust to surface | Uplift |
