Plate Tectonics & Plate Boundaries

the theory that explains how large pieces of the lithosphere, called plates, move and change shape the topography of the earth.

the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle

is the layer of the upper mantle composed of low-density rock matterial that is semiplastic,like putty.

where two plates are moving apart, magma comes up to create new crust

boundary between two colliding plates, often associated with mountain building ocean trenches and volcanic islands

boundary between two plates that are sliding past each other.

the process by which Earth's crust breaks apart; can occur within continental crust or oceanic crust

The continents of North America and Eurasia when all the continents were a single landmass.

The continents of Africa, South America, India, Australia, and Antarctica when all the continents were a single landmass.

What type of process is created by a divergent boundary.

When the earth's tectonic plates move, we call this a BLANK.

The vent on the earth's surface through which magma and gases are expelled is a called a BLANK.

When one tectonic plates dives under another, it is called BLANK.

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.

Japan is an example of an island BLANK.

California borders the BLANK plate and the North American Plate.

A BLANK boundary creates new ocean floor.

A BLANK boundary creates mountains.

In this boundary plates slide past each other.

In this boundary the plates come togehter.

In this boundary the plates move away from each other.

This place is in Africa and the plates are coming apart.

an underwater chain of mountains.

this type of ocean to ocean boundary would create a trench.

This country is an example of island arc.

Sea BLANK BLANK creates midocean ridges, earthquakes, and volcanic activity.

This is an example of a mid ocean ridge.

This is an example of sea floor spreading at a divergent boundary.

At a convergent convergent boundary where an ocean meets a continent, the ocean dives under. This is called BLANK>

_____ and _____ are features found at an ocean to continent convergent boundary.

This is an example of a subduction zone at a convergent boundary between a continent and an ocean.

T or F, a subduction zones would have earthquakre activity.

T or F, a subduction zone occurs where to plates move away from each other.

T or F California is an example of an island arc.

T or F Indonesian Islands are an example of an Island arc.

T or F A divergent boundary would create mountains.

T or F there are only two types of convergent boundaries.

T or F Japan is an example of an island arc.

T or F You will find earthquake activity in a continent to continent convergent boundary.

A transform boundary creates mountains.
