4. What are the three types of volcanoes?

5. Shield Volcanoes These volcanoes are low and flat and have flowing eruptions. As the lava builds up on the volcano it becomes larger. Shield volcano

6. Composite Volcanoes These volcanoes have tall mountain like structures. Mount St. Helens was a famous composite volcano. A crater at the top is where the lava flows out. Composite volcano

7. Cinder Cone Volcanoes These volcanoes are the simplest kind of volcanoes. They have a bowl-shaped crater where lava comes out. When lava flows over the top it creating the rocks called cinders. Cinder cone volcano

9. Why do volcanoes occur?

10. Occurring volcanoes Volcanoes occur when the Earths plates pull apart causing magma to rise to the surface. This is called plate tectonics.

11. What is plate tectonics?

12. Plate Tectonics Plate tectonics is the study of the motion of the plates in the Earths crust. The Earths tectonic plates are in constant motion.

13. Section 3

14. Where do most volcanoes occur?

15. They form around the Pacific Ring of Fire. There are many volcanoes in Hawaii also. Pacific Ring of Fire

16. How did the Pacific Ring of Fire get its name?

17. Pacific Ring of Fire The ring of fire is roughly shaped like a ring. It marks the area of the greatest seismic activity in the world. Tons of volcanoes occur here everyday.

18. How do volcanoes form?

19. ERUPTION!!! A volcano is formed when magma comes up from the Earth and through the cracks in its surface. A volcanoes magma makes up the Earths surface. A volcano is really cooled lava. A volcano erupting

20. What is a hot spot?

21. Hot Spot A hot spot is a flow of magma that pushes through areas of weakness on the Earths crust. Picture of Hot Spot

22. Section 4

23. What is a volcano hazard?

24. Volcano Hazards Danger from a volcanoes destruction is called a volcano hazard. In the past 500 years 200,000 people have lost their lives due to volcanoes. Destroyed homes

25. What hazards can volcanoes produce that effect people?

26. Destruction The accumulation of ash can affect peoples lungs. The ash is so small that it can easily get in your lungs. The ash

27. How do you get prepared for a volcano?

28. Pack a first aid kit. For the first aid kit you should provide the following: Flashlight Extra batteries Extra food and water Medicines Dust mask

29. Section 5

30. What is our favorite volcano in history?

31. Mount St. Helens During the past 4,000 years, Mount St. Helens has erupted more frequently than any other volcano in the Cascade Range. Most of Mount St. Helens is younger than 3,000 years old.

32. Mount St. Helens The first sign of activity at Mount St. Helens in the spring of 1980 was a series of small earthquakes that began on March 16.

33. Section 6

34. What is our favorite presently active volcano?

35. Mount Aso Mount Aso is one of the largest volcanoes from those seen all over the world This active volcano is located in Japan on an island called Kyushu. Mt. Aso’s crater

36. How do people live by Mount Aso?

37. People’s lives There are many big cities close to active volcanoes. People don’t seem to mind it that they could be apart of a huge disaster at any time.
