16. Earth Layers
The Earth is divided into four main
layers.
*Inner Core
*Outer Core
*Mantle
*Crust

17. 3
Crust
* The crust is the thin outer
layer of the Earth
* It varies from around 3 to 5
miles thick in the ocean floor
to around 25 miles thick on
land.
* Earth's crust is found on
the outer surface and it is
made of solid rock and
minerals.
J
(Rigid crust nd Upper
Mantle)
Is the dividing line between
the Crust and the Mantle.

18. TheCrust
• 2 types of crust
– Oceanic (very dense,
made of basalt)
– Continental (lessdense,
made of granite)

19. The Mantle
*The mantle is the next layer of the Earth.
* The mantle is thicker than the crust at
almost 1,900 miles deep and makes up
about 85% of the Earth's weight.
* The mantle is made up of slightly
different silicate rocks with more iron and
magnesium.
Isthe outer layer ofthe
mantle.

20. Core
Beneath the mantle is
the Earth's core. The
Earth's core consists of
a fluid outer core and a
solid inner core.

21. Outer Core
* The Earth's outer core is
made up of hot liquid iron
and nickel and is about
1,400 miles thick to thick
* The outer core creates
something called a magnetic
field and makes a protective
barrier around the Earth.
* The outer core is liquid.

22. Inner Core
* The Earth's inner core is
made up of solid iron and
nickel and is about 1,500
miles thick
* It's as hot as the Sun
surface around 9,000 to
13,000 degrees Fahrenheit
* The inner core is a solid.
