To solve this rock cycle diagram, we need to match the processes from the Word Box to the arrows showing how rocks change from one type to another. Let’s go step by step around the cycle.
---
Step 1: From Igneous Rock → Sediments
Igneous rock breaks down into small pieces called sediments. This happens through
weathering & erosion.
→ So, the arrow from *Igneous rock* to *Sediments* =
Weathering & erosion
---
Step 2: From Sediments → Sedimentary Rock
Sediments get pressed together and glued into solid rock. That’s called
deposition, compaction, & cementation.
→ Arrow from *Sediments* to *Sedimentary rock* =
Deposition, compaction, & cementation
*(Note: The blank box above “Sedimentary rock” is likely meant for this label — it’s pointing to the process that turns sediments into sedimentary rock.)*
---
Step 3: From Sedimentary Rock → Metamorphic Rock
When sedimentary rock gets buried deep underground, heat and pressure change it into metamorphic rock.
→ Arrow from *Sedimentary rock* to *Metamorphic rock* =
Heat & pressure
---
Step 4: From Metamorphic Rock → Magma
If metamorphic rock gets even hotter, it melts into magma.
→ Arrow from *Metamorphic rock* to *Magma* =
Melting
---
Step 5: From Magma → Igneous Rock
When magma cools down (like after a volcano erupts), it hardens into igneous rock.
→ Arrow from *Magma* to *Igneous rock* =
Cooling
---
Now let’s assign each blank box in order (going clockwise starting from top):
- Top center box (above Sedimentary rock) → Process turning sediments into sedimentary rock →
Deposition, compaction, & cementation
- Right side box (between Sedimentary and Metamorphic) →
Heat & pressure
- Bottom right box (between Metamorphic and Magma) →
Melting
- Bottom left box (between Magma and Igneous) →
Cooling
- Left side box (between Igneous and Sediments) →
Weathering & erosion
Wait — looking at the diagram again:
There are 5 blank boxes total:
1. Top center (above “Sedimentary rock”) → should be the process forming sedimentary rock from sediments →
Deposition, compaction, & cementation
2. Right vertical box (next to arrow from Sedimentary → Metamorphic) →
Heat & pressure
3. Bottom right diagonal box (arrow from Metamorphic → Magma) →
Melting
4. Bottom left diagonal box (arrow from Magma → Igneous) →
Cooling
5. Left vertical box (arrow from Igneous → Sediments) →
Weathering & erosion
Yes — that matches all 5 blanks with the 5 terms in the word box.
Let’s double-check no term is used twice or missed:
Word Box has:
- Weathering & erosion
✔ (used on left)
- Heat & pressure
✔ (right)
- Melting
✔ (bottom right)
- Cooling
✔ (bottom left)
- Deposition, compaction, & cementation
✔ (top center)
Perfect — all accounted for.

Final Answer:
Top center box:
Deposition, compaction, & cementation
Right box:
Heat & pressure
Bottom right box:
Melting
Bottom left box:
Cooling
Left box:
Weathering & erosion
