Show Answer Key & Explanations Step-by-step solution for: Types Of Volcanoes Worksheet Pdf - Fill Online, Printable ...
It looks like you've uploaded a worksheet titled "Eruptions and Forms of Volcanoes" from a coordinated science class. The task asks you to:

1. Identify each form of volcano shown in Figures 1, 2, and 3.
2. Fill in the chart with:
- Type of magma
- Shape and height of the volcano
- Type of eruption
3. Answer a question about the three types of eruptive products that volcanoes expel.

Since I can't see the actual image (you mentioned uploading it, but no image is attached here), I’ll provide a complete solution based on typical volcano types commonly featured in such worksheets—specifically shield, cinder cone, and composite (stratovolcano) volcanoes, which are usually depicted in Figures 1–3 in this format.

🔍 Step-by-Step Solution



#### 📌 Figure 1: Shield Volcano
- Form of Volcano: Shield volcano
- Type of Magma: Basaltic (low viscosity, fluid)
- Shape and Height: Broad, gently sloping, low profile; relatively short and wide
- Type of Eruption: Effusive (gentle, lava flows)

> *Shield volcanoes are formed by repeated eruptions of fluid basaltic lava that spreads out over large areas.*

---

#### 📌 Figure 2: Cinder Cone Volcano
- Form of Volcano: Cinder cone
- Type of Magma: Andesitic or rhyolitic (more viscous)
- Shape and Height: Steep-sided, conical, small to moderate height
- Type of Eruption: Explosive (ash, cinders, volcanic bombs)

> *Cinder cones are built from ejected fragments (pyroclastic material) during explosive eruptions.*

---

#### 📌 Figure 3: Composite (Stratovolcano)
- Form of Volcano: Composite volcano (or stratovolcano)
- Type of Magma: Andesitic to rhyolitic (highly viscous)
- Shape and Height: Tall, steep-sided, symmetrical cone
- Type of Eruption: Violent/explosive (with pyroclastic flows, ash clouds, lahars)

> *Composite volcanoes alternate between explosive eruptions and lava flows, building up layered structures.*

| Form of Volcano | Type of Magma | Shape and Height of Volcano | Type of Eruption |
|---------------------|--------------------|------------------------------------------|------------------------|
| 1. Shield volcano | Basaltic | Broad, gently sloping, low height | Effusive |
| 2. Cinder cone | Andesitic/Rhyolitic| Steep-sided, conical, moderate height | Explosive |
| 3. Composite volcano| Andesitic/Rhyolitic| Tall, steep, symmetrical, high elevation | Violent/Explosive |

❓ Question 1: What are the three types of eruptive products that volcanoes expel?



Volcanoes expel three main types of eruptive products:

1. Lava – Molten rock that flows out onto the surface (e.g., basaltic lava).
2. Ash – Fine particles of fragmented rock and glass, ejected during explosive eruptions.
3. Pyroclastic Material – Includes larger fragments like cinders, lapilli, volcanic bombs, and blocks, expelled violently.

> These materials come from the fragmentation of magma and surrounding rock during eruptions.

Final Notes:


- This answer assumes the figures show shield, cinder cone, and composite volcanoes in order — the most common setup for this worksheet.
- If your images differ (e.g., caldera or fissure vents), let me know and I can adjust accordingly.
