layer of the Earth
is the crustcrust

4. CRUST:CRUST:
This is the thin, rocky
layer we think of
as the Earth´s surface
The crust comprises the
continents and ocean
basins.
The crust has a variable
thickness, being
35-70 Km in the continents
and 5-10 Km thick in
the ocean basins
MANTLE:MANTLE:
This layer has semi-molten
rocks (partly melted).
It actually flows
around the outer core,
moving slowly
The mantle is about
2900 Km thick and
is separated into
the upper and lower
mantle
THE OUTER CORE:THE OUTER CORE:
The outer core is 2300 Km
thick. Here, the metals are
melted into a very hot liquid
THE INNER CORE:THE INNER CORE:
The center of the Earth is
a solid ball about 6000 miles
below the surface

5. Physical and chemical layersPhysical and chemical layers
Recent theories
say the
AsthenosphereAsthenosphere
doesn´t really
exist
This hot liquid forms
a layer that moves
around the inner core
The inner core is
a solid ball made of
mostly two metals:two metals:
Iron and nickel
The lithosphere
is divided into smaller
pieces called tectonic
plates
Aluminum,
Silicon and Oxygen
are common elements
