FREE Types of Rocks Worksheets (inlcudes Rock Life Cycle Diagram) - Free Printable

The image you've uploaded is a Rock Cycle worksheet designed to help students understand how the three main types of rocks—igneous, sedimentary, and metamorphic—are formed and transformed over time through various geological processes.

Let’s break down what's happening in the diagram and solve the task.

🔍 Understanding the Rock Cycle

The rock cycle illustrates how rocks are continuously transformed from one type to another through natural processes like erosion, heat, pressure, melting, and cooling.

There are three main rock types:

1. Igneous Rock: Formed when magma (underground) or lava (above ground) cools and solidifies.
2. Sedimentary Rock: Formed when sediments (like sand, silt, or clay) are compacted and cemented together over time.
3. Metamorphic Rock: Formed when existing rocks are subjected to high heat and/or pressure, changing their mineral composition and texture.

📝 Analyzing the Diagram

The worksheet has three panels:

#### ✔ Left Panel:
- Shows a volcanic eruption → igneous rock → sedimentary rock
- Arrows indicate transformation steps.
- This shows only part of the cycle.

#### ✔ Middle Panel:
- Lists the four key components with images:
1. Volcanic eruption
2. Igneous rock
3. Sedimentary rock
4. Metamorphic rock
5. Lava / magma
- There are blank lines next to each — likely for students to write the processes that form or transform these rocks.

#### ✔ Right Panel:
- A blank version of the cycle with arrows and images of rocks and volcanoes.
- Students are expected to label the missing parts (likely the names of rock types and processes).

🧩 Task: Complete the Rock Cycle

We need to fill in the blanks in the right panel based on the flow of the rock cycle.

Let’s go step-by-step using standard rock cycle knowledge:

---

🔁 Step-by-Step Rock Cycle Flow

1. Volcanic Eruption → Lava flows out and cools → becomes Igneous Rock
- So: Volcanic eruption → Igneous rock

2. Igneous Rock undergoes weathering and erosion → breaks into sediments → sediments are compacted and cemented → become Sedimentary Rock

3. Sedimentary Rock is buried deep underground → exposed to heat and pressure → becomes Metamorphic Rock

4. Metamorphic Rock can be heated further → melts into magma/lava

5. Magma/Lava cools → forms new Igneous Rock → cycle repeats

---

✔ Filling in the Right Panel

Looking at the right side of the worksheet:

- Top: Volcanic eruption → leads to igneous rock (already shown)
- Then: igneous rock → arrow → sedimentary rock (after weathering/erosion/deposition)
- Then: sedimentary rock → arrow → metamorphic rock (due to heat/pressure)
- Then: metamorphic rock → arrow → lava/magma (melting due to extreme heat)
- Then: lava/magma → arrow → volcanic eruption (erupts and cools)

So the labels should be:

1. Volcanic eruption → igneous rock
2. Igneous rock → sedimentary rock
3. Sedimentary rock → metamorphic rock
4. Metamorphic rock → lava / magma
5. Lava / magma → volcanic eruption

---

✏️ Final Answer: Labels for the Right Panel

Label the blanks in the right panel as follows:

- After volcanic eruption: igneous rock
- After igneous rock: sedimentary rock
- After sedimentary rock: metamorphic rock
- After metamorphic rock: lava / magma
- After lava / magma: volcanic eruption

---

🔁 Summary of Processes (for middle panel):

| Image | Process |
|------|--------|
| Volcanic eruption | Cooling of lava/magma |
| Igneous rock | Formed by cooling of lava/magma |
| Sedimentary rock | Formed by compaction and cementation of sediments |
| Metamorphic rock | Formed by heat and pressure on existing rocks |
| Lava / magma | Melting of rocks under high temperature |

---

✔ Conclusion

To complete this worksheet:

1. Right Panel: Label each stage in the cycle:
- Volcanic eruption → igneous rock → sedimentary rock → metamorphic rock → lava/magma → volcanic eruption

2. Middle Panel: Write the processes that create each rock type:
- Igneous rock: Cooling and solidification of magma/lava
- Sedimentary rock: Compaction and cementation of sediments
- Metamorphic rock: Heat and pressure
- Lava/magma: Melting of rocks

This completes the rock cycle diagram accurately.
