Inside a Volcano - educational diagram illustrating key volcanic features.

Let's solve this labeling task step by step using the provided diagram and the word bank.

Word Bank:

- ash cloud
- crust
- crater
- central vent
- lava
- side vent

---

Step-by-step Analysis of the Diagram:

1. Top of the volcano (cloud-like shape):
- This is a plume rising from the volcano.
- The label points to a dotted cloud above the volcano.
- This is clearly an ash cloud, which forms when volcanic eruptions eject ash into the atmosphere.

2. Opening at the top of the volcano:
- This is the crater — the bowl-shaped depression at the summit where lava, ash, and gases erupt.

3. Main vertical channel from deep underground to the crater:
- This is the central vent — the main conduit through which magma travels upward to the surface.

4. Side openings on the volcano’s slope:
- These are side vents — smaller openings that allow lava or gases to escape laterally.

5. Molten rock flowing out of the volcano:
- The material flowing down the slopes is lava — magma that has reached the Earth’s surface.

6. Layer beneath the volcano (bottom layer):
- The solid outer layer of the Earth is the crust — the uppermost layer of the Earth's surface.

Now, let's fill in the blanks:

From the diagram:

- Top left (dotted cloud): → ash cloud
- Top center (opening at summit): → crater
- Middle (vertical tube from depth to crater): → central vent
- Side opening on slope: → side vent
- Flowing material coming out: → lava
- Bottom layer (Earth’s surface layer): → crust

---

✔ Final Answer with Labels:

- Top dotted cloud: ash cloud
- Summit opening: crater
- Main vertical pipe: central vent
- Side opening on flank: side vent
- Material flowing down: lava
- Bottom layer: crust

📌 Summary:

The diagram illustrates the internal structure of a volcano. Using the word bank, we correctly label each part based on its function and location:

- Ash cloud = eruption plume
- Crater = top opening
- Central vent = main conduit
- Side vent = lateral opening
- Lava = molten rock on surface
- Crust = Earth’s outer layer

This helps students understand how magma moves from deep within the Earth to erupt at the surface.
