  1. Volcanoes Eric Pergine

  2. Main Menu Please follow each of the links for the different types of volcanoes and then answer the multiple choice review question when you finish the lesson. • Types of Volcanoes • Cinder Cones • Composite Volcanoes • Shield Volcanoes • Lava Volcanoes • Review Question

  3. Cinder Cones Cinder cones are the most common type of volcanoes. They are circular cones made up of fragments of lava from a single vent that have been blown into the air, and cooled around the vent.

  4. Examples of Cinder Cones A good example of a Cinder Cone is Paracutin in Mexico. Paracutin Paracutin Erupting

  5. Composite Volcanoes Composite Volcanoes are steed sided structures made up of many layers of volcanic rock, usually made by very thick lava, ash, and debris. Due to the multiple layers, these volcanoes can erupt for an extended amount of time.

  6. Examples of Composite Volcanoes Two famous examples of composite volcanoes are Mt. Rainier and Mt. St. Helens, both found in Washington State. Mount St. Helens Mount Rainier

  7. Shield Volcanoes Shield Volcanoes are large volcanoes composed of mainly fluid lava flows. These volcanoes have very broad sides and often look like large shields. Shield Volcanoes may be the product of hot spots which are far away from the edges of tectonic plates. They can also be found along mid-ocean ridges.

  8. Examples of Shield Volcanoes An example of a Shield Volcano is the island of Hawaii. The big island is made of five different volcanoes, and the smaller islands are made up of their own volcanoes as well. Kilauea, Hawaii Mauna Loa, Hawaii

  9. Lava Volcanoes Also known as lava domes, lava volcanoes are formed when erupting lava is too thick to flow and creates a steep mound as it piles up near the volcanic vent. The eruption of Mt. St. Helens was partially caused by a lava dome shifting to allow explosive gas out of the mountain.

  10. Examples of Lava Volcanoes A few examples of lava volcanoes can be located in North America. First, there is Lassen Peak, California. Next, there is a lava volcano located in Alaska, called Novarupta. Lassen Peak, CA Novarupta, AK

  11. Volcanoes review question Mt. St. Helens and Mt. Rainier are both famous examples in America of what type of volcano? • Cinder Cones • Composite Volcanoes • Shield Volcanoes

  12. Try again! Oops! That answer is incorrect. Paracutin in Mexico is an example of a Cinder Cone.

  13. Correct! Good Job! You are correct! Mt. St. Helens and Mt. Rainier are both prime examples of Composite Volcanoes in America!

  14. Try again! Oops! The answer is incorrect. Shield Volcanoes in America are found in Hawaii, such as Kilauea.

  15. Congratulations! You have completed this lesson on Volcanoes! Well Done! Click the arrow to return to the title slide for the next student.
