Plate 

Tectonics

The large 

land mass 

of all 

earth's 

continents 

joined 

together 

300 million 

years ago.

Plate tectonics is the theory that 

the outer rigid layer of the earth 

(the lithosphere) is divided into a 

couple of dozen "plates" that 

move around across the earth's 

surface relative to each other.

The scientist 

that proposed 

the idea of 

continental 

drift.

The theory by 

Alfred Wegener 

that Earth's 

continents 

were all once 

joined together 

millions of 

years ago.

Sections of the earth's crust and upper mantle that 

move across the earth, as stated in the theory of 

plate tectonics.

Earth's Interior

The outermost layer of the earth which is 

broken up into pieces called plates.

The outer part if earth consisting of crust 

and upper mantle.

A zone of the earth's mantle that lies 

beneath the lithosphere.

Located beneath the crust, magma is stored 

here and moves about through convection 

currents which moves the plates.

Located beneath the mantle where there's hot, 

plastic-like rock flowing.

Located beneath the outer core and is the 

hottest place in the interior of the earth.

The state of being a solid and also have the 

ability to flow like a liquid.

Boundaries

A place where plates slide past each other, 

which can cause an                            .
