Tectonic plates
Matter that is not exactly solid and
not exactly liquid, but is still able to
flow.
Crust
An area where many earthquakes
occur and where there is frequent
volcanic activity.
Mantle
Hot molten rock released onto the
surface of the Earth’s crust that
solidifies to form new layers of
rock.
Is composed mainly of Fe.
Outer core
Inner core
Are produced when hot, molten
rock forces its way to the surface.
Subduction
The region on the crust where two
tectonic plates meet.
Earthquakes
Rips in the crust caused by tectonic
plates moving away from each
other.
Pacific Ring of Fire
Produced when tectonic plates
move suddenly.
Volcanoes
Hot, molten rock underneath the
surface of the crust.
Magma
Caused by the intense heat of the
core causing material in the mantle
to rise.
Lava
The thin, solid layer of the
Earth.
Plate boundaries
An area under the crust where one
tectonic plate slides under another.
Ocean trenches
A layer of the Earth which is
molten.
Earth’s magnetic field
Movement in this layer causes the
tectonic plates to move.
Convection currents
Large pieces of the crust.
Plastic
Assumed to be caused by the inner
core spinning at a different speed
to the rest of the earth.
