🔍 Understanding the Rock Cycle

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

Here are the key processes and transformations:

| Process | Result |
|--------|--------|
| Cooling of magma/lava → Igneous rock |
| Weathering & erosion → Sediments |
| Deposition, compaction, cementation → Sedimentary rock |
| Heat & pressure → Metamorphic rock |
| Melting → Magma |

✔ Step-by-Step Filling of Boxes

We need to fill in the blanks in each box based on the process shown.

---

#### 🔹 1. Deposition, compaction, & cementation
This process turns sediments into sedimentary rock.

> Sediments → Sedimentary rock

✔ Fill in:
Sediments → Sedimentary rock

---

#### 🔹 2. Heat & pressure
This transforms igneous or sedimentary rocks into metamorphic rock.

> Igneous rock → Metamorphic rock
> Sedimentary rock → Metamorphic rock

✔ Fill in:
Igneous rock → Metamorphic rock
Sedimentary rock → Metamorphic rock

---

#### 🔹 3. Cooling
This turns magma into igneous rock.

> Magma → Igneous rock

✔ Fill in:
Magma → Igneous rock

---

#### 🔹 4. Melting
This turns igneous, sedimentary, or metamorphic rocks into magma.

> Igneous rock → Magma
> Sedimentary rock → Magma
> Metamorphic rock → Magma

✔ Fill in:
Igneous rock → Magma
Sedimentary rock → Magma
Metamorphic rock → Magma

---

#### 🔹 5. Weathering & erosion
This breaks down rocks into sediments.

> Igneous rock → Sediments
> Sedimentary rock → Sediments
> Metamorphic rock → Sediments

✔ Fill in:
Igneous rock → Sediments
Sedimentary rock → Sediments
Metamorphic rock → Sediments

---

✔ Final Answer Key (Filled Boxes)

#### 1. Deposition, compaction, & cementation
→ Sediments → Sedimentary rock

#### 2. Heat & pressure
→ Igneous rock → Metamorphic rock
→ Sedimentary rock → Metamorphic rock

#### 3. Cooling
→ Magma → Igneous rock

#### 4. Melting
→ Igneous rock → Magma
→ Sedimentary rock → Magma
→ Metamorphic rock → Magma

#### 5. Weathering & erosion
→ Igneous rock → Sediments
→ Sedimentary rock → Sediments
→ Metamorphic rock → Sediments

📌 Summary of Rock Types:

- Magma: Molten rock beneath Earth’s surface.
- Igneous rock: Formed from cooled magma/lava.
- Sediments: Broken-down fragments of rocks.
- Sedimentary rock: Formed from compacted sediments.
- Metamorphic rock: Formed from existing rocks under heat/pressure.

✔ The rock cycle is continuous — rocks can change form over time due to natural processes like heat, pressure, weathering, and melting.
