Parts of a volcano interactive worksheet - Free Printable

Let's solve this step-by-step by identifying the labeled parts of the volcano diagram using the word bank provided:

Word Bank:

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

---

Step 1: Understand the structure of a volcano

A typical volcano has:
- A central vent – the main channel through which magma rises.
- A crater – the bowl-shaped depression at the top where eruptions occur.
- Lava – molten rock that flows out during an eruption.
- Side vents – smaller openings on the sides of the volcano where lava can also escape.
- Ash cloud – a plume of volcanic ash and gases erupted into the air.
- Crust – the outer layer of the Earth, shown at the base.

Step 2: Match each label to the correct part in the diagram

We’ll go through each arrow and identify what it points to.

#### 1. Arrow pointing to the cloud above the volcano
- This is the ash cloud – the plume of ash and gas rising from the volcano.
✔ Label: ash cloud

#### 2. Arrow pointing to the top opening of the volcano
- This is the crater, where eruptions happen.
✔ Label: crater

#### 3. Arrow pointing to the main vertical pipe inside the volcano
- This is the central vent – the main conduit for magma/lava to rise.
✔ Label: central vent

#### 4. Arrow pointing to the side opening on the volcano slope
- This is a side vent – a secondary opening where lava can erupt.
✔ Label: side vent

#### 5. Arrow pointing to the flowing material coming out of the side vent
- This is lava – molten rock flowing down the side.
✔ Label: lava

#### 6. Arrow pointing to the outer layer at the bottom of the diagram
- This is the crust – the Earth’s outer solid layer.
✔ Label: crust

Final Answer (Labels in order of arrows):

1. Top cloud → ash cloud
2. Top opening → crater
3. Central pipe → central vent
4. Side opening → side vent
5. Flowing material → lava
6. Bottom layer → crust

Completed Diagram Labels:

```
[ash cloud] → cloud
[crater] → top opening
[central vent] → main vertical pipe
[side vent] → side opening
[lava] → flowing material
[crust] → bottom layer
```

✔ All terms from the word bank are used exactly once.
