Plate Tectonics & Plate Boundaries
Arc
Japan is an example of an island BLANK.
False
T or F A divergent boundary would create mountains.
False
T or F California is an example of an island arc.
True
T or F Indonesian Islands are an example of an Island arc.
True
T or F Japan is an example of an island arc.
True
T or F You will find earthquake activity in a continent to continent convergent boundary.
False
T or F there are only two types of convergent boundaries.
False
T or F, a subduction zone occurs where to plates move away from each other.
True
T or F, a subduction zones would have earthquakre activity.
Volcano
The vent on the earth's surface through which magma and gases are expelled is a called a BLANK.
Convergent
A BLANK boundary creates mountains.
Divergent
A BLANK boundary creates new ocean floor.
Pacific Ring of Fire
A major volcanic zone which is found along the Pacific ocean and travels all the way from South America, to North America and along Asia.
False
A transform boundary creates mountains.
Subduction
At a convergent convergent boundary where an ocean meets a continent, the ocean dives under. This is called BLANK>
Pacific
California borders the BLANK plate and the North American Plate.
Transform
In this boundary plates slide past each other.
Convergent
In this boundary the plates come togehter.
Divergent
In this boundary the plates move away from each other.
Sea floor spreading
Sea BLANK BLANK creates midocean ridges, earthquakes, and volcanic activity.
Gondwanaland
The continents of Africa, South America, India, Australia, and Antarctica when all the continents were a single landmass.
Laurasia
The continents of North America and Eurasia when all the continents were a single landmass.
Japan
This country is an example of island arc.
Mid Atlantic Ridge
This is an example of a mid ocean ridge.
Western Coast of South America
This is an example of a subduction zone at a convergent boundary between a continent and an ocean.
East Pacific Rise
This is an example of sea floor spreading at a divergent boundary.
Great African Rift
This place is in Africa and the plates are coming apart.
Sea Floor spreading
What type of process is created by a divergent boundary.
Subduction
When one tectonic plates dives under another, it is called BLANK.
Earthquake
When the earth's tectonic plates move, we call this a BLANK.
Volcanoes and Earthquakes
_____ and _____ are features found at an ocean to continent convergent boundary.
Midocean ridge
an underwater chain of mountains.
Convergent boundary
boundary between two colliding plates, often associated with mountain building ocean trenches and volcanic islands
Transform boundary
boundary between two plates that are sliding past each other.
Asthenosophere
is the layer of the upper mantle composed of low-density rock matterial that is semiplastic,like putty.
Rifting
the process by which Earth's crust breaks apart; can occur within continental crust or oceanic crust
Lithosphere
the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
Plate Tectonics
the theory that explains how large pieces of the lithosphere, called plates, move and change shape the topography of the earth.
Convergent
this type of ocean to ocean boundary would create a trench.
Divergent boundary
where two plates are moving apart, magma comes up to create new crust
