Complete the rock cycle diagram by filling in rock types, examples, and processes involved in their transformation.

Let's solve the Rock Cycle worksheet step by step. The diagram shows a circular flow of rock types and the processes that transform one type into another. We’ll fill in each blank with the correct rock type, examples, and the process involved.

🔁 Understanding the Rock Cycle

The rock cycle involves three main types of rocks:
1. Igneous Rocks – Formed from cooled magma/lava.
2. Sedimentary Rocks – Formed from sediments compacted and cemented.
3. Metamorphic Rocks – Formed when existing rocks are changed by heat and pressure.

Processes include:
- Melting → Magma
- Cooling → Igneous rock
- Weathering & erosion → Sediments
- Deposition, compaction, & cementation → Sedimentary rock
- Heat & pressure → Metamorphic rock

🧩 Step-by-step Completion:

We'll go around the cycle clockwise starting from the volcano (magma) at the bottom.

#### 🔹 1. Bottom center: Volcano (Magma)
- Box: Magma
- Examples: (none — magma is molten rock, not solid yet)
- Process leading to next stage: Cooling

> From magma → cooling → igneous rock

---

#### 🔹 2. Top right: Crystalline rock (granite-like texture)
- Box: Igneous rock
- Examples: basalt, granite
- Process from magma: Cooling
> Magma cools → forms igneous rock

---

#### 🔹 3. Right side: Layered or striped rock
- Box: Metamorphic rock
- Examples: quartzite, marble
- Process from igneous rock: Heat & pressure
> Igneous rock subjected to heat and pressure → metamorphic rock

---

#### 🔹 4. Bottom right: Rounded rock (sediment)
- Box: Sediments
- Examples: sand, gravel
- Process from metamorphic rock: Weathering & erosion
> Metamorphic rock breaks down → sediments

---

#### 🔹 5. Bottom left: Flat sedimentary rock
- Box: Sedimentary rock
- Examples: sandstone, limestone
- Process from sediments: Deposition, compaction, & cementation
> Sediments get compacted and cemented → sedimentary rock

---

#### 🔹 6. Top left: Crystalline rock again? Wait — back to magma?
Wait — the arrow goes from sedimentary rock → magma, but how?

Actually, the cycle should show:
- Sedimentary rock → melting → magma

So:
- Box: Magma (again, completing the cycle)
- Process from sedimentary rock: Melting
> Sedimentary rock melts → magma

But wait — we already had magma at the bottom. So let’s recheck the diagram.

Looking at the arrows:
1. Magma → Igneous rock (cooling)
2. Igneous rock → Metamorphic rock (heat & pressure)
3. Metamorphic rock → Sediments (weathering & erosion)
4. Sediments → Sedimentary rock (deposition, compaction, cementation)
5. Sedimentary rock → Magma (melting)

✔ That completes the cycle.

✔ Final Filled Diagram:

#### 🔹 Top Box (between igneous and metamorphic):
- Box: Igneous rock
- Examples: basalt, granite
- Process from magma: Cooling

#### 🔹 Right Box (metamorphic rock):
- Box: Metamorphic rock
- Examples: quartzite, marble
- Process from igneous rock: Heat & pressure

#### 🔹 Bottom-right Box (sediments):
- Box: Sediments
- Examples: sand, gravel
- Process from metamorphic rock: Weathering & erosion

#### 🔹 Bottom-left Box (sedimentary rock):
- Box: Sedimentary rock
- Examples: sandstone, limestone
- Process from sediments: Deposition, compaction, & cementation

#### 🔹 Bottom-center (magma):
- Box: Magma
- Examples: (none)
- Process from sedimentary rock: Melting

🔄 Summary of the Rock Cycle Flow:

| Stage | Rock Type | Examples | Process |
|------|-----------|----------|--------|
| 1 | Magma | — | — |
| 2 | Igneous Rock | basalt, granite | Cooling |
| 3 | Metamorphic Rock | quartzite, marble | Heat & Pressure |
| 4 | Sediments | sand, gravel | Weathering & Erosion |
| 5 | Sedimentary Rock | sandstone, limestone | Deposition, Compaction, Cementation |
| 6 | Magma | — | Melting |

> Note: The cycle can start from any point, but typically begins with magma.

✔ Answer Key for Worksheet:

#### Fill in the blanks:

- Top box (after cooling): Igneous rock
- Examples: basalt, granite

- Right box (after heat & pressure): Metamorphic rock
- Examples: quartzite, marble

- Bottom-right box (after weathering & erosion): Sediments
- Examples: sand, gravel

- Bottom-left box (after deposition, compaction, cementation): Sedimentary rock
- Examples: sandstone, limestone

- Bottom-center (from melting): Magma
- Examples: (none listed — magma is not solid)

📝 Processes Between Stages:

1. Magma → Igneous rock: Cooling
2. Igneous rock → Metamorphic rock: Heat & pressure
3. Metamorphic rock → Sediments: Weathering & erosion
4. Sediments → Sedimentary rock: Deposition, compaction, & cementation
5. Sedimentary rock → Magma: Melting

💡 Tips for Students:

- Use the Word Box to pick correct terms.
- Remember: All rocks can become magma if melted.
- Igneous rocks are “born” from cooling magma.
- Sedimentary rocks form from layers of sediment.
- Metamorphic rocks change without melting.
