Rock Cycle Teaching Activity Worksheets - Free Printable

Let's solve the Rock Cycle worksheet step by step, based on the diagram and questions provided. The Rock Cycle illustrates how the three main types of rocks—igneous, sedimentary, and metamorphic—are transformed into one another over time through various geological processes.

🔁 The Rock Cycle Overview:

- Igneous Rock: Forms from cooled magma/lava.
- Sedimentary Rock: Forms from sediments compacted and cemented together.
- Metamorphic Rock: Forms when existing rocks are subjected to heat and pressure.

These rocks can transform into each other via processes like weathering, erosion, compaction, cementation, melting, cooling, and metamorphism.

✔ Answering Each Question:

1. Look at the igneous rock, what causes it to turn into sediment?
➤ Weathering and erosion break down igneous rock into smaller pieces (sediments).
→ *Answer:* Weathering and erosion

2. Look at the igneous rock, what causes it to break down into pieces (sediments)?
➤ This is the same as question 1.
→ *Answer:* Weathering and erosion

3. Look at the sedimentary rock, what causes it to turn into metamorphic rock?
➤ Heat and pressure deep underground change the mineral structure.
→ *Answer:* Heat and pressure

4. Look at the sedimentary rock, what causes it to turn into pieces (sediments)?
➤ Weathering and erosion break it apart again.
→ *Answer:* Weathering and erosion

5. Look at the metamorphic rock, what causes it to turn into pieces (sediments)?
➤ Again, weathering and erosion break it down.
→ *Answer:* Weathering and erosion

6. Look at the metamorphic rock, what causes it to turn into magma?
➤ When metamorphic rock is buried deeply and heated enough, it melts into magma.
→ *Answer:* High temperature (melting)

7. Look at the magma, what causes it to turn into igneous rock?
➤ Magma cools and solidifies (either underground or on surface).
→ *Answer:* Cooling and solidification

8. Look at the sediments, what causes them to become sedimentary rock?
➤ Sediments are compacted and cemented together.
→ *Answer:* Compaction and cementation

9. Look at any rock in the rock cycle, discuss three ways they journey to change.
➤ Any rock can be changed by:
- Weathering and erosion (breaks rock into sediments)
- Heat and pressure (forms metamorphic rock)
- Melting (turns rock into magma)
→ *Answer:* Rocks change via weathering/erosion, heat and pressure, and melting.

🔄 Visual Flow from Diagram (Numbered Arrows):

Let’s match the arrows in the diagram:

- Arrow 1: Igneous → Sediments → Weathering & Erosion
- Arrow 2: Sediments → Sedimentary → Compaction & Cementation
- Arrow 3: Sedimentary → Metamorphic → Heat & Pressure
- Arrow 4: Metamorphic → Magma → Melting
- Arrow 5: Magma → Igneous → Cooling & Solidification
- Arrow 6: Metamorphic → Sediments → Weathering & Erosion
- Arrow 7: Sedimentary → Sediments → Weathering & Erosion
- Arrow 8: Igneous → Magma → Melting (if deep enough)

> Note: Some arrows may be bidirectional depending on context.

✔ Final Summary Table:

| Question | Answer |
|--------|--------|
| 1 & 2 | Weathering and erosion |
| 3 | Heat and pressure |
| 4 | Weathering and erosion |
| 5 | Weathering and erosion |
| 6 | Melting (high temperature) |
| 7 | Cooling and solidification |
| 8 | Compaction and cementation |
| 9 | Weathering/erosion, heat and pressure, melting |

💡 Key Concept:

The rock cycle shows that all rocks can change into each other over time due to Earth's internal and external forces. No rock type is permanent — they are constantly being recycled!
