Let’s solve this step by step.
We have a word bank with these words:
Pacific, Conductor, Basalt, Lava, Igneous, Openings, Icecaps, Fault, Extinct, Magma, Cloud, Plates
And 12 sentences to fill in the blanks using those words.
---
Sentence 1:

---
Sentence 3:
*Over 75% of the Earth’s volcanoes are found in the ________ Ocean.*
→ Most volcanoes are along the “Ring of Fire,” which is mostly in the Pacific Ocean.
✔ Answer:

---
Sentence 4:
*Hot liquid rock found deep under the Earth’s surface is known as ________.*
→ That’s called magma (before it erupts).
✔ Answer:

---
Sentence 5:
*When magma erupts to the surface through a volcano, it’s called ________.*
→ Once it’s on the surface, we call it lava.
✔ Answer:

→ Three states: active (erupting), dormant (sleeping), extinct (dead/never will erupt again).
✔ Answer:
Extinct
---
Sentence 9:
*Volcanoes can be found on the ocean floor and even under ________.*
→ Some volcanoes are under ice! Like in Antarctica or Iceland. So “Icecaps” fits.
✔ Answer:
Icecaps

Sentence 10:
*Lava cools slowly because it is poor ________ of heat.*
→ Poor conductor means it doesn’t transfer heat well → so it cools slowly.
✔ Answer:
Conductor
---
Sentence 11:
*An ash ________ is formed by a volcanic explosion.*
→ Ash goes up into the air and forms a cloud.
✔ Answer:
Cloud
---
Sentence 12:
*A ________ is a crack or fracture in the Earth’s surface.*
→ That’s the definition of a fault.
✔ Answer:
Fault
---
All words used exactly once? Let’s check:
