This type of plate boundary typically results in the weakest volcanic eruptions.
What is a divergent boundary?
100
The Hawaiian Islands were created as the result of a spot underneath this tectonic plate.
What is the Pacific plate?
100
This type of volcano is very broad and has gradual slopes, it is often created from Basaltic lava and has several vents and cracks.
What is a Shield volcano?
100
Lava that has not yet reached the surface is commonly refered to as this.
What is magma?
100
This Hawaiian word means Basaltic lava that forms smooth ropelike surfaces.
What is Pahoehoe?
200
This type of plate boundary typically results in the most violent volcanic eruptions.
What is a subduction boundary?
200
The hot spot that created the Hawaiian Islands is currently located under this island.
What is the Big Island or Hawaii?
200
This type of volcano is created along a subduction boundary and is the result of several different volcanic eruptions. It is very often explosive during eruptions.
What is a Composite volcano?
200
Magma that has hardened underneath the surface forms this type of rock.
What is Igneous rock?
200
This Hawaiian word means Basaltic lava that forms rigid, and jagged surfaces.
What is aa?
300
This type of subduction boundary will create a line of volcanoes along the coast of a continent.
What is an oceanic - continental subduction boundary?
300
When plotting the movement of the tectonic plates and hot spots, you should graph the distance that the plate moves over this other factor.
What is the years the plate has been moving?
300
This type of volcano is formed by ash and pyroclastic materials that have been fired into the air and fall back to the mountain as small Igneous rock fragments creating a steep slope.
What is Cindercone volcano?
300
This type of magma that has a lower silica content and usually results in less violent volcanic eruptions.
What is Basaltic Magma?
300
This Hawaiian word means a mudslide caused by rapidly melting snow and ice during a volcanic eruption.
What is lahar?
400
This type of plate boundary is often going to result in earthquakes, but almost never in volcanic eruptions.
What is a transform boundary?
400
During the formation of the Hawaiian Islands the Hot spot remains stationary, but the tectonic plate moves in this direction.
What is Northwest?
400
This type of volcano is typically found along an oceanic hot spot or a divergent plate boundary.
What is a Shield volcano?
400
The reason that volcanic eruptions are more violent is because there is a higher __________ content in the Igneous rock.
What is Silica?
400
This word means the resistance of a liquid to flow, often refering to lava flow and volcanoes.
What is viscosity?
500
This type of plate boundary will result in very deep sea trenches and also in an arc of volcanicislands.
What is an oceanic - oceanic subduction boundary?
500
Hot spots are caused by a weakness in the lithosphere that allows materials from this area to rise to the surface.
What is the mantle?
500
This type of volcano is typically found where a continetal hot spot reaches the surface.
What is Cindercone volcano?
500
Composite volcanoes typically have a higher silica content and form more explosive volcanic eruptions. This means the volcanos is made from this type of magma.
What is Rhyolitic?
500
This is the most dangerous materials ejected from a volcano during and eruption. It is a super-heated cloud of gas and volcanic materials.
