1. Cornell Notes: Types of Volcanoes & Hot Spots

2. Topic / Objective:
Types of volcanoes and hot spots.
Essential Question:
How do different types of volcanoes look and behave?

3. What is a Shield Volcano?
Broad at the base and has gently sloping sides
Covers a wide area
Generally forms from quiet / nonexplosive eruptions
Example: Hawaiian Islands

4. Shield Volcano – Mount Kilauea, Hawaii

5. What is a cinder cone volcano?
Most common type of volcano
Very steep slopes
Forms from explosive eruptions
Made of pyroclastic material
Often found in clusters
Example: Paricutin, Mexico

6. Cinder Cone Volcano – Mount Paricutin, Mexico

7. What is a composite volcano?
Explosive and non explosive eruptions
Made of alternating layers of hardened lava flows (non-explosive) and pyroclastic material (explosive)
Also known as Stratovolcanoes
Example: Mt. Tambora and Mt. Fuji

8. Composite Volcano – Mount Fuji, Japan

10. What is a Hot Spot?
A hot spot is a volcanically active area of Earth’s surface, commonly far from a tectonic plate boundary
Most hot spots form where columns of solid, hot material from the deep mantle, called mantle plumes, rise and reach the lithosphere

12. Hawaiian Islands Formed as a Result of Hot Spots
Often the hot spot creates a chain of volcanoes, as a plate moves across a relatively stationary mantle plume. The best example of a hot spot volcanic chain is the Hawaiian Islands.
From the volcanic track left by the moving plate we can tell the direction of motion of the plate (to the NW) and the rate at which it moves (8.6 cm/year).
