1. Steep Slope 30-40 Degrees Cinder Cone

2. Medium to steep Slope 20-30 Degrees Composite Cone (Stratovolcano)

3. Gentle Slope 2-10 Degrees Shield Cone

4. Pyroclasts fall out of the air onto each other and build up piles of debris that are weekly cemented together or not cemented at all.
*They erode quickly.
Cinder Cone

5. Form from layers of ash and pyroclastic alternated with lava flows
Composite Cone
(Stratovolcano)

6. Form from layers from lava flows;Spreads over large areas and builds up much wider than tall.
Shield Cone

7. Moderately explosive to highly explosive Cinder Cone

8. Highly explosive with a great deal of pyroclastic material at some times and very quiet a(gentle eruptions) at other times.
Composite Cone
(Stratovolcano)

9. Nonexplosive, quiet eruptions with little pyroclastic material.
Shield Cone

10. Cinder Cone Smallest of the three basic types
Slightly more wide than tall.
Often less than 300m tall
Cinder Cone

11. Middle sized compared to the shield and cinder type.
Moderately more wide than tall.Often 2,000m to 2500m tall.
Composite Cone
(Stratovolcano)

12. Largest of the three basic types. Much more wide than tall
Largest of the three basic types. Much more wide than tall. As high as 17km tall.

Shield Cone

16. Cinder Cone -Often occur in clusters
-Usually erupt for short time and then
go extinct
-Often form on the sides of other
volcanoes
-Form at rift zones and convergent
boundaries
Cinder Cone

17. One of the most common types of volcano
One of the most common types of volcano.Form at subduction zones of convergent boundaries
Composite Cone
(Stratovolcano)

18. Often form over hot spots in the ocean.
This is the type of volcano that makes up the Hawaiian islands.
