Earth’s interior?
Do now: If we could take a x-ray
of the Earth, what kind of layers
do you think we will see?

the Earth's Interior?the
The Crust

Outer-most layer.
Varies in thickness
Continental crust
= thickest.
(especially under
mountains)
Oceanic crust =
thinnest.
What are the different properties of layers
of the Earth's Interior?the
felsic
mafic
What are the different properties of layers
of the Earth's Interior?the
Continental crust is
granitic (made of
granite)
Oceanic crust is
basaltic (made of
basalt)

Crust

The Crust is broken up into
many pieces called plates.
Crust resembles a cracked hardboiled egg.

The Mantel
Two parts: upper
mantel and lower
mantel.

Upper mantel
(asthenosphere)plastic
Lower mantel- rigid
(solid)

The Lithospheric
Plates

The crust of the Earth is broken into many pieces called
plates. The plates "float" on the soft, semi-rigid
What are the different properties of layers
of the Earth's Interior?the
asthenosphere.
The mantel is 2900 km deep.
It is the thickest layer.

The Outer Core

The outer core
is a liquid layer.
Composed of
the metals
nickel and iron.

The Inner Core
 The inner core
is a solid.
Has the highest
temperature and
the highest
pressure.


The proof for the
properties of the
interior of the
Earth is in the
Seismic waves

waves)

The Four Layers

The Earth is composed of four
different layers. The crust is
the layer that you live on, and
it is the most widely studied
and understood. The mantle
is much hotter and has the
ability to flow. The outer
core and inner core are
even hotter with pressures so
great you would be squeezed
into a ball smaller than a
marble if you were able to go
to the center of the Earth!
