The Rock Cycle in the Earth's Crust - Educational worksheet for learning rock types and transformation processes.

Absolutely! Let’s complete “The Rock Cycle in the Earth’s Crust” worksheet step by step, using the word box provided.

🌋 Understanding the Rock Cycle

The rock cycle shows how the three main types of rocks — igneous, sedimentary, and metamorphic — transform into one another through geological processes like melting, cooling, weathering, erosion, deposition, compaction, cementation, and heat & pressure.

We’ll fill in the diagram clockwise, starting from the volcano (which represents magma/igneous activity).

## 🔁 Step-by-Step Filling of the Diagram

---

1. Top Box: Magma

➡️ Process: Magma is molten rock beneath the Earth’s surface. When it cools and solidifies, it becomes igneous rock.

✔ Fill in top box: `Magma`

✔ Process to next rock (igneous): `Cooling`

---

2. Top Right Box: Igneous Rock

➡️ Formed when magma cools and solidifies.

✔ Label this box: `Igneous rock`

✔ Examples: `basalt, granite` *(from word box)*
*(Basalt = extrusive, fine-grained; Granite = intrusive, coarse-grained)*

✔ Process to next rock (sediments): `Weathering & erosion`
*(Breaks down igneous rock into small pieces)*

---

3. Bottom Right Box: Sediments

➡️ Fragments of rocks/minerals broken down by weathering and erosion.

✔ Label this box: `Sediments`

✔ Examples: `sand, gravel` *(from word box)*

✔ Process to next rock (sedimentary): `Deposition, compaction, & cementation`
*(Sediments settle, get pressed together, and glued into solid rock)*

---

4. Bottom Left Box: Sedimentary Rock

➡️ Formed from compacted and cemented sediments.

✔ Label this box: `Sedimentary rock`

✔ Examples: `sandstone, limestone` *(from word box)*

✔ Process to next rock (metamorphic): `Heat & pressure`
*(Deep burial or tectonic forces change sedimentary rock into metamorphic rock)*

---

5. Top Left Box: Metamorphic Rock

➡️ Formed when existing rocks are changed by heat and pressure.

✔ Label this box: `Metamorphic rock`

✔ Examples: `quartzite, marble` *(from word box)*
*(Quartzite from sandstone; Marble from limestone)*

✔ Process back to magma: `Melting`
*(If metamorphic rock melts deep underground, it becomes magma again)*

## 🔄 The Full Cycle Summary:

Magma → (Cooling) → Igneous Rock → (Weathering & Erosion) → Sediments → (Deposition, Compaction, Cementation) → Sedimentary Rock → (Heat & Pressure) → Metamorphic Rock → (Melting) → Magma

✔ All words used from the Word Box:
- Magma
- Igneous rock
- Sediments
- Sedimentary rock
- Metamorphic rock
- Melting
- Weathering & erosion
- Heat & pressure
- Cooling
- Deposition, compaction, & cementation
- sand, gravel
- sandstone, limestone
- quartzite, marble
- basalt, granite

*(Note: “Igneous rock” appears twice — once as label, once in examples — but that’s okay since it’s part of the process.)*

## 🧠 Bonus Explanation for Students:

> Rocks are never “done” — they’re always changing! The rock cycle has no true start or end. For example:
> - A granite mountain can be weathered into sand, which becomes sandstone.
> - That sandstone might get buried and become quartzite.
> - If it melts, it becomes magma again!
>
> This cycle has been happening for billions of years and shapes our planet’s surface.
