8.2.2 Practice: The Yellowstone Supervolcano Practice Assignment
Kristina McClamrock

Answer the following questions thoroughly.
1. Draw a diagram of a volcano. Make sure you label the magma chamber, central vent, side vents, and crater. (5 points)

On a seperate sheet.


2. What are three characteristics of magma that cause a volcano to have a huge eruption? (12 points)

Gas, lava and tephra cause a volcano to have a huge eruption.

3. Volcanoes are able to form in several different plate-tectonic settings.
A. How does a hot-spot supervolcano (such as Yellowstone) form? (5 points)

Magma does not reach the surface of a supervolcanoe and just fills resevoirs. The magma melts rock and makes it reall thick. Pressure builds up in that area, because the magma is so thick that gases cannot pass through it, thus creating a hot spot.

B. What type of volcano is Mount Saint Helens? (2 points)

Mount St. Helens is of the composite type.

C. How is the formation of this type of volcano different than that of a hot-spot volcano? (3 points)

They erupt different ways, from slow seeping and violent explosions. The layers that make up composite cone volcanoes alternate between lava flows and pyroclastic flows.


4. Most hot-spot volcanoes erupt through oceanic crust.
A. Do these hot-spot volcanoes tend to erupt more explosively than other volcanoes? (5 points)

No they do not erupt more explosively. It depends on its gas and its viscosity.

B. What is an example of a hot-spot volcano that supports your answer? (4 points)


Kilauea in Hawaii does not erupt more explosive.

5. Why do oceanic hot-spot volcanoes often form a long line of volcanic islands? (10 points)


Because the lithospheric ocean plate moves with plate tectonics over the stationary mantle based hot spot, forming a series of volcanoes.


6. The Internet is flooded with information on the Yellowstone supervolcano. What are two characteristics you use to determine if Web sites will have accurate information? (4 points)

Well usually .org and .edu sites are reliable. If the web site itself cites a long line of sources, then usually it's reliable. If it looks official and has a copy right date, it could be reliable.

2. What are three characteristics of magma that cause a volcano to have a huge eruption? (12 points)

Gas, viscosity and silica.

3. Volcanoes are able to form in several different plate-tectonic settings.
A. How does a hot-spot supervolcano (such as Yellowstone) form? (5 points)


Magma does not reach the surface of a supervol2canoe and just fills resevoirs. The magma melts rock and makes it reall thick. Pressure builds up in that area, because the magma is so thick that gases cannot pass through it, thus creating a hot spot.

This is because the hotspot stays in the same place, but the ocean crust moves over it. It erupts when the crust isn't stable, so it erupts.

B. What type of volcano is Mount Saint Helens? (2 points)

Subductions zone from the East coast.

C. How is the formation of this type of volcano different than that of a hot-spot volcano? (3 points)

One is formed through mass amounts of subduction, and the other includes no subductions. It lays under the crust.
