=Volcanoes=




 * A volcano is an opening is an opening in a planets surface or crust, which allows hot molten rock through the surface.
 * Volcanoes are found where tectonic plates pull apart or come together.
 * Example: Mid Atlantic Ridge has plates pulling apart.
 * Volcanoes are usually not created when two tectonic plates slide against one another.
 * Volcanoes are usually not created when two tectonic plates slide against one another.

6 types of volcano eruptions

 * The most common types of volcanoes are Hawaiian, Strombolian, Plinian and Vulcanian eruptions.
 * the most dangerous volcano is a dormant volcano that erupts after several hundred years without activity. If this volcano has not been studied in detail or if it is near a major population center, geologists will have to rush to learn about it, predict its behavior, and protect the people. They will also need to deploy instruments and solve numerous logistical and technological problems.
 * You can tell what type of volcanic eruption when it erupts, because they are very different how thy erupt
 * (Example: Pelean eruption's ash and lava go down the volcano and while the vulcanian eruption's ash and lava shoot out like fire works.)

//Why do volcanoes erupt?//
//answer: When rock inside the Earth becomes hot enough it melts. This molten rock, or magma, is less dense than the surrounding solid rock. Just as an object that is less dense than water will float on water, the relatively low density of the magma cause it to rise to the surface of the Earth.

If the magma contains waqter and dissolved gases, when the magma reaches the surface the water and dissolved gases will suddenly expand into steam and gas, causing a violent eruption.//

//(Example: This is like shaking a can of coke and then popping the tab.)//

Script
__Nikhil Derick Linda-Jean Mi Young__

Everyone: Hi! we are the deadly volcano group and we started recording on November 13, 2007.

Nikhil: Welcome to the deadly volcano group. We will tell you some facts about volcanoes. WA Hah hah hah hah. *Cough cough* Excuse me!!! As I was saying we are going to be presenting some facts about volcanoes. Now here is Derick with the first question.

Derick: I am really stumped on this question. I don’t know the different types of eruptions. Linda- Jean please tell me the answer.

Linda-Jean: The different types of eruptions are Hawaiian, Strombolian, Plinian, Vulcanian, Icelandic and Pelean.

Mi young: Hey Nikhil! Do you know how volcanoes form?

Nikhil: Yeah! When magma comes out of the ground suddenly it hardens and piles up like a small mountain. After some years this pile grows to become a volcano. This is the process of how volcanoes form.

Mi Young: Wow so fascinating!

Nikhil: Derick can you tell me the difference between lava and magma?

Derick: Sure why not! The difference is that magma is molten rock beneath the surface as where as lava is molten rock that has erupted on the surface.

Linda-Jean: Nikhil can you tell me why volcanoes don’t form near cities?

Nikhil: Volcanoes need space to form and if they did form near cities people would go screaming from here to there like this: Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhh every time the volcano erupts.

Linda-Jean: So that's why volcanoes don't form near cities.

Derick: Hey! Mi Young please answer my question. Which is the most active volcano on Earth?

Mi Young: The most active volcano on Earth is Mt. Etna in Italy. It has been erupting for 3,500 years.

Derick: Ooooooooooooooooh!

Nikhil: Um Derick I need to ask you something. Do earthquakes occur below the volcano before it erupts? Huh Huh Huh Huhhhhhhhhhhhhh?

Derick: O.k? Earthquakes do occur below the volcano before it erupts.

Mi Young: Do you know which was the largest volcano eruption in History?

Linda-Jean: The largest volcano eruption in history was the eruption of the volcano Tambora. It blasted volcanic bombs 100 Km away.

Derick: Nikhil, can you tell me where and when the last volcano erupted?

Nikhil: The last volcano erupted in Rabaul, New Zealand last year.

Mi Young: Are there any volcanoes that have similarities between them for elevation?

Derick: Yes there are volcanoes that have similarities between them for elevation. For example Mt. Fuji in Japan and Mt. Ararat in Turkey.

Derick: Do you know how far anyone has gone in an extinct volcano crater?

Mi Young: The farthest that anyone has gone inside a volcano is only 5000 ft.

Nikhil: What kinds of islands have underwater volcanoes made?

Derick: The major ones are Japan,New Zealand,the Caribbean Islands,the Philippines, Indonesia,and the Aleutian Islands.

Everyone: Thank You for listening to our presentation. We hope you enjoyed it. Hah Hah Hah Hah Hah Hah Hah Hah Haaaaahhhhhhhh!

Movies
This movie shows you about the different lava flows and the eruptions of the volcano. The different types of lava flows are Hawiian, plinian, vulcanion, icelandic, strombolian and pelean. The name of the eruptions are the same name as the lava flow. This movie also shows a lot of active volcanoes which have recently been erupting.There is also a map of the ring of fire and other active volcanoes below the movie. First watch the movie and then see the map. So enjoy and watch the fascinating movie of volcano eruptions and lava flows.
