Let’s solve this step by step.

First, we need to fill in the blanks in the paragraph using the words from the word bank:

Word Bank:
solid, Metamorphic, Igneous, melt, magma, erosion, buried, Sedimentary, pressure, weathering, Cycle

---

Step 1: First sentence — “There are three main types of rocks: Igneous, Sedimentary and ________.”

We know the three main rock types are Igneous, Sedimentary, and Metamorphic. So the first blank is Metamorphic.

---

Step 2: “Each of these types of rocks can be turned into each other in a process known as the Rock ________.”

This is called the Rock Cycle. That’s the name of the whole process shown in the diagram.

---

Step 3: “Most rocks on earth began as an ________ rock which are formed from cooled ________.”

Igneous rocks form when magma cools and hardens. So:

- First blank: Igneous
- Second blank: magma

(Note: Magma is molten rock underground; lava is above ground — but here it says “cooled”, so magma fits.)

---

Step 4: “The wind and rain breaks the rock down into smaller pieces called sediments. This process is called ________ and ________.”

Breaking down rocks = weathering
Carrying away the pieces = erosion

So: weathering and erosion

---

Step 5: “Over time, the rock will be ________ by many more pieces of rock and they stick together forming a new type of rock called ________ rock.”

When layers pile up, the bottom layer gets buried. Then it becomes Sedimentary rock.

So: buried, then Sedimentary

---

Step 6: “When the Sedimentary rock is buried deep under the earth’s surface, the heat and ________ the rock turning it into a Metamorphic rock.”

Heat and pressure change sedimentary rock into metamorphic rock.

Blank: pressure

---

Step 7: “The Metamorphic rocks ________ in the heat and turn into magma.”

Rocks melt to become magma. So: melt

---

Now let’s put all the answers in order for the paragraph:

There are three main types of rocks: Igneous, Sedimentary and Metamorphic.
Each of these types of rocks can be turned into each other in a process known as the Rock Cycle.
Most rocks on earth began as an Igneous rock which are formed from cooled magma.
The wind and rain breaks the rock down into smaller pieces called sediments. This process is called weathering and erosion.
The wind and water carry the sediments into lakes and rivers, and they sink to the bottom. Over time, the rock will be buried by many more pieces of rock and they stick together forming a new type of rock called Sedimentary rock.
When the Sedimentary rock is buried deep under the earth’s surface, the heat and pressure the rock turning it into a Metamorphic rock.
The Metamorphic rocks melt in the heat and turn into magma. If this magma is cooled either by shooting out of a volcano or uplifting towards the Earth’s surface, then they will turn back into a rock and become an Igneous rock once more.

Wait — one small fix: In the sentence “the heat and ________ the rock turning it into...” — grammatically, it should probably say “the heat and pressure change the rock...” but since “change” isn’t in the word bank, and “pressure” is the only missing word that fits, we’ll go with pressure — assuming the verb is implied or typo’d.

Actually, looking again — the sentence says: “the heat and ________ the rock turning it into...”

That seems like a grammar error in the original. But since “pressure” is the only logical choice from the word bank, and it’s paired with heat to cause metamorphism, we’ll use pressure.

Final check: All words used? Let’s list what we used:

Used: Metamorphic, Cycle, Igneous, magma, weathering, erosion, buried, Sedimentary, pressure, melt

Leftover: solid — not needed? Wait, maybe we missed something?

Looking back — no, “solid” doesn’t fit anywhere naturally. Maybe it’s a distractor? Or perhaps in the diagram labeling part? But the user didn’t ask us to label the diagram — only to complete the paragraph.

The instruction was: “Complete the following paragraph using the correct vocabulary.”

So we’ve filled all blanks correctly with available words. “Solid” may be extra or for another part (like labeling the diagram), but since the question focuses on the paragraph, we’re good.

Also note: The diagram has 3 boxes to label — likely pointing to Igneous (volcano area), Sedimentary (layered near water), and Metamorphic (deep underground). But since the user didn’t ask to label them explicitly, and the main task is the paragraph, we focus there.

But wait — the very top says: “Can you use the information from the story of Smasher to label the types of rock correctly?” — but no story is given. Probably “Smasher” is a character in a related story not provided. Since we don’t have that, we rely on standard rock cycle knowledge.

Given that, our paragraph answers are solid.

Final Answer:

Metamorphic
Cycle
Igneous
magma
weathering
erosion
buried
Sedimentary
pressure
melt
