Volcano Worksheets - Free Printable

It looks like you've uploaded an image of a worksheet titled "Classifying Volcanic Cones", which asks students to identify and label different types of volcanic cones based on their shapes. The worksheet includes three diagrams of volcanoes, each representing a different type: Cinder Cone, Shield Volcano, and Composite (Stratovolcano).

Here’s how to solve the task step-by-step:

---

🔍 Step 1: Understand the Three Types of Volcanic Cones

1. Cinder Cone
- Shape: Steep-sided, conical hill.
- Formation: Built from loose fragments of lava (cinders) ejected during explosive eruptions.
- Eruption Style: Explosive, short-lived.
- Example: Parícutin in Mexico.

2. Shield Volcano
- Shape: Broad, gently sloping sides like a shield.
- Formation: Formed by low-viscosity lava that flows easily and spreads out.
- Eruption Style: Effusive (non-explosive).
- Example: Mauna Loa in Hawaii.

3. Composite Volcano (Stratovolcano)
- Shape: Tall, steep-sided with alternating layers of lava, ash, and rock.
- Formation: Built up by multiple eruptions—both explosive and effusive.
- Eruption Style: Alternating explosive and quiet eruptions.
- Example: Mount St. Helens or Mount Fuji.

🖼️ Step 2: Match Each Diagram to the Correct Type

Let’s analyze the three diagrams shown in the image:

#### ✔ Diagram A (Left):
- Has a steep, conical shape with a crater at the top.
- No wide base; appears small and compact.
- This is a Cinder Cone.

> 🔹 Label: Cinder Cone

#### ✔ Diagram B (Middle):
- Very broad and flat, with gentle slopes.
- Wide base and low profile.
- This is a Shield Volcano.

> 🔹 Label: Shield Volcano

#### ✔ Diagram C (Right):
- Tall and steep, with a layered appearance.
- Shows alternating deposits and a large crater.
- This is a Composite (Stratovolcano).

> 🔹 Label: Composite Volcano

✔ Final Answers:

| Diagram | Volcanic Cone Type |
|--------|--------------------------|
| A | Cinder Cone |
| B | Shield Volcano |
| C | Composite Volcano |

📝 Additional Task:

The worksheet also says: *"For each, provide the names of the features labeled using the diagram below."*
But since no labels are visible in your image (likely due to resolution), here's what common labels might be:

- Crater – The bowl-shaped depression at the summit.
- Lava flow – Streams of molten rock flowing down the slope.
- Vent – Opening through which magma erupts.
- Ash cloud – Plume of ash and gas (especially for cinder and composite).
- Pyroclastic deposits – Rock fragments ejected during explosion (common in composite).

🧠 Summary:

To classify volcanic cones:
- Cinder cone = steep, small, explosive.
- Shield volcano = broad, gentle slopes, fluid lava.
- Composite volcano = tall, steep, layered, explosive.

✔ Answer Key (Final Labels):
- Diagram A: Cinder Cone
- Diagram B: Shield Volcano
- Diagram C: Composite Volcano
