Famous Volcanoes
This volcano erupted in the Philippines in 1991.
what isMt. Pinatubo?
Plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other.
What are Subduction zones?
Chains of volcanoes that are caused by partial melting of the plate at a subduction zone.
What are Island arcs?
Are made of different minerals that have different melting points; therefore, magma can vary in composition.
What are rocks?
Viscosity which is the internal flow of magma.
What is magma composition?
This famous volcano erupted on May 18th, 1980 killing 185,193 in the United States.
What is Mt. St. Helens?
Occurs in a horseshoe shape around the edge of the Pacific Ocean, offshore of Washington state, Canada, Alaska, Russia, Japan and Indonesia and down to New Zealand and the southern edge of South America.
What are Subduction Zone>
Begins to heat up as it descends into the lithosphere and eventually melts .
What are the subducting plate?
Forms when rocks melt.
What is Magma?
Sticky, thick, and resist flowing, much like putty.
What is viscosity?
This volcano is the world's largest, active volcano rising 2.5 miles above sea level.
What is Mauna Loa, Hawaii?
Subduction occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth's interior.
What boundaries cause subduction?
What type of tectonic plates cause islands?
Magma contains two kinds of dissolved gases.
What carbon dioxide and hydrogen sulfide?
Locations can be oceanic and continental crust.
What is Basaltic magma?
According to some experts, if this volcano ever became active, it would be the biggest catastrophe in the world.
What is the Yellowstone?
The Cascadia Subduction Zone, extending from northern California through western Oregon and Washington to southern British Columbia.
What are types of convergent boundaries?
Island arcs are long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries.
What areconvergent tectonic plate boundaries?
This is the plastic like portion of the mantle underneath the lithosphere.
What is the Athenosphere?
. Location is around the continental crust, and it is very explosive.
What isRhyolitic magma?
This volcano in Japan has is about 78 miles in circumference and 30 to 40 miles in diameter.
What is Mount Fuji?
Forms an arc when two oceanic plates converge creating a row of islands above the overriding plate.
What are islands?
Collides against each other, the older and therefore heavier of the two subducts beneath the other, initiating volcanic activity
What are two oceanic plates?
Influences whether a rock will melt besides pressure and temperature.
What is water>
.This type of volcano is highly dangerous to humans.
What are composite cones?
