Tectonic Plates



At the centre of the earth there is a
solid ball. Made of Solid Iron and
Nickel, this is known as the Core



Around the Core is the Mantle,
semi-molten rock. The mantle
moves very slowly.



The outer layer of the core is the
crust, it is very…

Tectonic Plates



There are three types of plate
margins;
­

Destructive Plate Margins; Where an
oceanic plate meets a continental plate,
the oceanic plate is forced down, into the
mantel and is destroyed. An example of
were you can find a Destructive plate
margin is along the east coast of…

Tectonic Plates



Constrictive Margins:
­

Constructive plate margins are were two
plates move away from each other.
­

Magma and molten rock rises from the
mantle to fill the gap and cools creating a
new crust. An example of the margin can
be found at the mid-Alatnic ridge.

Tectonic Plates



Conservative Margins;
­

Conservative margins are two plates
moving next to each other, either in
different directions of the same but at
different speeds.
­

Crust is not created nor destroyed. The
type of crust can be found at the West
Coast of the USA

Fold Mountains



Fold Mountains are created when
plates collide at Destructive Plate
Margins.



When Tectonic plates collide the
sedimentary rocks that have built up
between them are folded and forced
up to create antinomians



You get fold mountains where a
Continental Plate and an Oceanic
plate collide.
