Volcanoes Labelling Activity Answers - Identify the internal structure of a volcano.

Let's solve the "Volcanoes Labelling Activity" by matching the correct terms to the parts of the volcano shown in the diagram.

Step 1: Understand the vocabulary

Here are the terms provided:
- Vent
- Crater
- Magma chamber
- Ash cloud
- Lava
- Conduit pipe
- Layers of solid lava

Now, let’s identify each part of the volcano based on typical volcanic structure:

Step 2: Analyze the diagram

Looking at the diagram (a cross-section of a volcano), we can identify:

1. Topmost part (cloud-like shape above the volcano)
→ This is the ash cloud, formed during an eruption.

2. Opening at the top of the volcano
→ This is the crater, the bowl-shaped depression at the summit.

3. The narrow tube or channel leading from the magma chamber to the surface
→ This is the conduit pipe.

4. The opening through which lava and gases escape
→ This is the vent, often located at the crater.

5. The large underground reservoir of molten rock
→ This is the magma chamber, deep beneath the volcano.

6. The flowing molten rock coming out of the vent
→ This is lava (note: lava is molten rock *above* ground; magma is below).

7. The hardened layers building up the sides of the volcano
→ These are layers of solid lava, forming the cone.

Step 3: Match labels to arrows

Now, match the words to the blank boxes with arrows pointing to specific parts.

From the image layout (based on standard diagrams):

- Top right arrow pointing to the cloud → ash cloud
- Arrow pointing to the top opening → crater
- Arrow pointing to the central vertical tube → conduit pipe
- Arrow pointing to the side opening where lava flows out → vent
- Arrow pointing to the molten rock flowing out → lava
- Arrow pointing to the large underground chamber → magma chamber
- Arrow pointing to the sloped layers of the volcano → layers of solid lava

Final Answer (Labeling):

1. Top right box (cloud) → ash cloud
2. Top center box (crater) → crater
3. Middle right box (vertical tube) → conduit pipe
4. Middle left box (side opening) → vent
5. Bottom left box (flowing material) → lava
6. Bottom middle box (deep chamber) → magma chamber
7. Bottom right box (layers on slope) → layers of solid lava

Summary of Labels:

| Box Position | Label |
|--------------|---------------------|
| Top right | ash cloud |
| Top center | crater |
| Middle right | conduit pipe |
| Middle left | vent |
| Bottom left | lava |
| Bottom middle| magma chamber |
| Bottom right | layers of solid lava|

✔ All terms are used exactly once.

This completes the labeling activity correctly!
