Rock Cycle Review KEY | PDF | Sedimentary Rock | Rock (Geology) - Free Printable

Let’s go step by step through each question using the rock cycle diagram and basic geology knowledge.

---

Question 1:
As magma cools, it forms IGNEOUS rock by the process (what happens), of SOLIDIFICATION (COOLING AND CRYSTALLIZING).
✔ This is already correctly answered in the image. Magma → solidifies → igneous rock.

---

Question 2:
Igneous rocks can form SEDIMENTARY, METAMORPHIC and IGNEOUS rocks.
✔ Correct. Igneous rock can:
- Weather/erode → sediments → sedimentary rock
- Be heated/pressured → metamorphic rock
- Melt → magma → new igneous rock

---

Question 3:
Sediments form SEDIMENTARY ROCK by the process (what happens), of DEPOSITION, BURIAL, COMPACTING, AND CEMENTING.
✔ Correct. Sediments get buried, squished (compacted), and glued together (cemented) to become sedimentary rock.

---

Question 4:
Sediments form from the process (what happens), of WEATHERING AND EROSION.
✔ Correct. Rocks break down (weathering) and are moved away (erosion) to become sediments.

---

Question 5:
Sedimentary rocks can form IGNEOUS, METAMORPHIC and SEDIMENTARY rocks.
✔ Correct. Sedimentary rock can:
- Melt → magma → igneous rock
- Be heated/pressured → metamorphic rock
- Weather/erode → sediments → new sedimentary rock

---

Question 6:
Which process (what happens), changes igneous rock into metamorphic rock?
Answer given: HEAT AND PRESSURE CHANGES IGNEOUS ROCK INTO METAMORPHIC ROCK.
✔ Correct. Metamorphism = heat + pressure without melting.

---

Question 7:
Which process (what happens), changes sedimentary rock into igneous rock?
Answer given: MELTING (MAGMA) THEN SOLIDIFICATION (COOLING AND CRYSTALLIZING).
✔ Correct. Sedimentary rock must melt first to become magma, then cool to become igneous rock.

---

Question 8:
Which process (what happens), changes metamorphic rock into sedimentary rock?
Answer given: WEATHERING AND EROSION TO BECOME SEDIMENTS, THEN DEPOSITION, BURIAL...
✔ Almost correct — but let’s finish the thought clearly.

Metamorphic rock doesn’t turn directly into sedimentary rock. It must first be broken down into sediments via weathering and erosion. Then those sediments go through deposition, burial, compaction, and cementation to become sedimentary rock.

So the full answer should include both steps:
→ Weathering & erosion → sediments → deposition, burial, compaction, cementation → sedimentary rock.

The answer in the image cuts off at “BURIAL.” We need to complete it.

Now, since all questions except #8 are fully and correctly answered, and #8 is partially correct but incomplete, we’ll provide the corrected final version for #8.

But note: The user did not ask us to correct or improve — they uploaded an image with answers already filled in. However, per instructions, we are to solve the problem accurately. Since Q8’s answer is cut off, we must complete it properly.

Also, note that the worksheet has 8 questions, and all are answered — but Q8 is incomplete. So our job is to verify and complete if needed.

Looking again at Q8 in the image:

> 8. Which process (what happens), changes metamorphic rock into sedimentary rock?
> WEATHERING AND EROSION TO BECOME SEDIMENTS, THEN DEPOSITION, BURIAL.

It stops at “BURIAL” — missing “compacting and cementing”.

In geology, the full process to turn sediments into sedimentary rock is:
Deposition → Burial → Compaction → Cementation

So the complete answer should end with “...then deposition, burial, compaction, and cementing.”

---

Final check: All other answers are accurate. Only Q8 needs completion.

Since the instruction says “solve the problem accurately”, and the problem includes answering all 8 questions, we will output the corrected full answer for Q8 as part of the Final Answer section — but only if required.

Wait — actually, looking back: the user uploaded a completed worksheet. Are we supposed to grade it? Or just confirm correctness?

Re-reading the prompt: “Solve the problem accurately.” And the “problem” is the set of 8 questions on the rock cycle.

Even though answers are written in, we are to treat this as solving the homework — meaning, we must ensure each answer is correct and complete.

Therefore, for Q8, we must supply the full correct answer.

Also, note: In Q3, the answer says “DEPOSITION, BURIAL, COMPACTING, AND CEMENTING” — which is correct.

So for consistency, Q8 should say the same after “sediments”.

Thus, corrected Q8 answer:

WEATHERING AND EROSION TO BECOME SEDIMENTS, THEN DEPOSITION, BURIAL, COMPACTION, AND CEMENTATION.

(“Compacting” vs “compaction” — either is acceptable, but “compaction” is more standard.)

---

Now, since ExplainAnswer, TeachTopic, and GeneratePractice are all false, we skip those sections.

We only output the Final Answer — which should be the complete, verified answers to all 8 questions.

But wait — the original image already has answers filled in. Should we repeat them all? Or only fix Q8?

The instruction says: “Solve the problem accurately.” The problem is the entire worksheet. So we must present the correct answers to all 8 questions — even if some were already correct.

However, to avoid redundancy, perhaps we only list the ones that need correction? But the format requires “Final Answer” to contain the final correct answer — implying the full solution.

Given that, and to be safe, I will list all 8 answers in their correct, complete form — especially fixing Q8.

But note: Questions 1–7 are already correct as written in the image. Only Q8 is incomplete.

So in Final Answer, I’ll write:

For questions 1–7: [correct as shown]

For question 8: [completed version]

But the format says “Provide only the final correct answer” — so likely, we should output the full set of answers as they should appear.

Alternatively, since the student may have submitted this and wants verification, but the task is to “solve”, I think best practice is to output the complete correct answers for all 8.

Let me structure it cleanly.

──────────────────────────────────────

Final Answer:
1. As magma cools, it forms igneous rock by the process of solidification (cooling and crystallizing).
2. Igneous rocks can form sedimentary, metamorphic, and igneous rocks.
3. Sediments form sedimentary rock by the process of deposition, burial, compacting, and cementing.
4. Sediments form from the process of weathering and erosion.
5. Sedimentary rocks can form igneous, metamorphic, and sedimentary rocks.
6. Heat and pressure change igneous rock into metamorphic rock.
7. Melting (to form magma) then solidification (cooling and crystallizing) changes sedimentary rock into igneous rock.
8. Weathering and erosion break metamorphic rock into sediments; then deposition, burial, compaction, and cementation form sedimentary rock.

(Note: For Q8, the original answer was cut off after “burial”; we added “compaction, and cementation” to complete the process.)

This ensures accuracy and completeness.
