  1. Dangerous Volcanoes By: Claire

  2. Volcanoes are located a lot of different places. Many times they are on edges of continents because of plate tectonics. Volcanoes are located where the earth’s plates meet. They also are located in hotspots like Hawaii and Japan. You can also find them on the ocean floor. The Pacific ring of fire is a place on the basin of the pacific where many volcanic eruptions happen. Where Are Volcanoes Typically Located?

  3. Imagine a volcano as if it were a soda can. If it has gas and steam in it when you pop the tab it will expand and….BOOM! Why do Volcanoes Erupt?

  4. Volcanoes erupt with lava/magma which is molten rock and is very hot but moves somewhat slowly. It also explodes with gas and pyroclasts (rock fragments). Everything that comes out of a volcano is at an extreme temperature because it is from deeper down in the ground and it’s hot down there! What Comes Out Of Volcanoes?

  5. Volcanoes erupt whenever they need to release stress. The volcano has gas and lava building up in side of it like a soda can after be shaken. How Often do Volcanoes Erupt?

  6. Normally, when a volcano erupts it explodes with lava and gas that can be very deadly. Volcanoes leave very, very big damage such as mudslides, tearing houses apart, and much more. They leave damage What Happens When a Volcano Erupts?

  7. Volcanoes are measured on a scale from 0-8. 0-1 volcanic eruptions happen often and are not big deals. 2-4 eruptions happen about 1 time every year. 5 volcanoes are more rare and happen about every 10 years, give or take a few. 6 volcanoes only happen about once every 100 years! 7s happen every 1000 years! 8 volcanic eruptions happen almost every 1,000,000 years and are the most rare. How are Volcanoes Measured?

  8. Damage from a volcano includes mud/landslides, lava flow, and layers of ash. Are There Any After Effects?

  9. Mountain Ranges are features that are involved with volcanoes. Hotspots are also involved with volcanoes, hotspots are places like Hawaii. These are where tectonic plates meet. What Structures and Features are Involved with Volcanoes?

  10. Magma/Lava- Molten rock • Ash Fall- A cloud of ash from a volcanic eruption • Tectonic Plates- the plates inside the earth that meet and make volcanoes • Volcano- Basically, a big mountain with a hole at the top and connects to an underground chamber of lava • Chamber- The place under a volcano that holds the lava Volcano Words
