1. Which process describes when solid rock turns into liquid magma?

2. What happens during crystallization?

3. Which processes help break down existing rocks? (Check all that apply)

4. During deformation, rocks can:

5. Fill in the blank: Sedimentation occurs when particles settle in _________ over time.

6. What provides the energy that drives melting deep inside Earth?

7. Explain how energy flows through Earth's materials cycle. Give at least two examples.

8. What would happen to Earth's materials cycle if there was no heat energy from Earth's interior?

9. Draw arrows and label the cycle: Start with "Melting" and show how materials move through all five processes (melting → crystallization → deformation → weathering → sedimentation → back to melting).

10. Choose one process from your model-building activity. Describe how your group demonstrated this process using the classroom materials.

11. How might this Earth materials cycle affect the landscape in Howard County, Maryland? Think about local rivers, rocks, or landforms.
