What is lava?
The name for magma that rises to the earth's surface
|
What is along plate boundaries?
Places where volcanoes are most likely to form
|
What is viscosity?
Resistency to flow is called a liquid's..
|
What is a shield volcano?
This volcano is built out of layers of gently flowing basaltic lava
|
What is volcanic ash?
Fine grained tephra is called this
|
|
What is tephra?
Solid fragments of rock that build volcanoes such as cinder cone and composite
|
What is plate boundaries at several close locations.
The reason why so many volcanoes form around the "Ring of fire"
|
What is the compostion of the magma?
This controls the way that a volcano erupts
|
What is a cinder cone volcano?
This volcano has steep sides, composed of basaltic lava and develops from layers of tephra
|
What is burying human and wildlife habitats
The greatest danger of lahar
|
|
What is because it is less dence and more buoyant?
The reason magma rises towards the surface of the Earth
|
What is a hot spot located near the Hawaiian Islands?
The reason why there are so many volcanoes on the Hawaiian Islands.
|
What is EXPLOSIVELY!?
The type of erruption that occurs when there is a high amount of dissolved gas in the magma.
|
What is a composite volcano?
This volcano has alternating layers of tephra and lava that develop from its quiet and explosive erruptions
|
What is acidic rain?
Gas emissions from volcanoes can form this in the atmosphere, which is hazardous to animals and plants
|
|
What is a vent?
The central, circular or oval shaped opening of a volcano from which magma erupts
|
What is convergent?
The Californian volcanic arc forms because of this type of plate boundary
|
What is basaltic?
Magma and lava that has low silica and low viscosity
|
What is composite?
Mount Shasta is an example of this type of volcano
|
What is pyroclastic flow?
a rapidly moving mixture of hot gases and solids that is extremely dangerous
|
|
What is fissure eruption?
When magma escapes from narrow and elongated cracks in the earth's surface.
|
What is Juan De Fuca plate?
The name of the plate that is responsible for forming the Calfornian volcanic arc
|
What is grantic?
Magma and lava that has high silica and high viscosity
|
What is all of them?
The type(s) of volcanoes found in California
|
What is
-contaminating the water supplies -ash mixes with water to create lahar which moves quickly and can bury habitats -ash can bury plants and animals and their food sources
This is an effect of volcanic ash on the environment.
