PARTS OF EARTH

2. Parts of
the earth

4. Inner Core
Solid
Outer Core
Liquid
Mantle
Crust
Lithosphere – Crust and
Upper Layer of the Mantle
Layer of the Mantle
(asthenosphere) that
consists of hot rock of
tar-like consistency,
which slowly moves

5. The Crust
* The Earth’s crust is
like the skin of an
apple. It is very thin
compared to the other
three layers.
The crust makes up
1% of the Earth.
The crust of the
Earth is broken into
many pieces called
plates.
In crust metamorphic,
and sedimentary rocks
ect .
Earth's mantle and crust
formed about 100 million
years after the formation
of the planet about 4.6ago

6. • Thinnest layer of the Earth that ranges from only 2
miles in some areas of the ocean floor to 75 miles deep
under mountains
• Made up of large amounts of silicon and aluminum
• Two types of crust: oceanic crust and continental crust
• Composed of plates on which the continents and
oceans rest
Ocean Land

7. The Mantle
The mantle is the
layer below the crust.
The mantle is the
largest layer of the
Earth.
The mantle is divided
into two regions: the
upper and lower
sections.
Earth's mantle is an
average thickness of
2,886 kilometres The
mantle makes up about
84% of Earth's
volume.It is
predominantly solid
but it behaves as a
very viscous fluid.

8. • Solid but capable of flow (like hot asphalt )
• Thickest layer of the Earth (making up 70% of
the Earth’s mass)
• The hot material (magma) in the mantle rises
to the top of the mantle, cools, then sinks,
reheats, and rises again. These convection
currents cause changes in the Earth’s surface

9. Outer Core
* The core of the
Earth is like a ball
of very hot metals.
* The outer core is
liquid.
* The outer core is
made up of iron and
is very dense.

10. Outer
Core
• Molten (liquid) metal that is about 4,700°C
(8,500°F)
• Located about 1,800 miles beneath the
crust and is about 1,400 miles thick
• Composed of the melted metals nickel and
iron

11. Inner
Core
• Solid sphere composed mostly of iron
• It is believed to be as hot as 6,650°C (12,000°F)
• Heat in the core is probably generated by the
radioactive decay of uranium and other elements
• It is solid because of the pressure from the outer
core, mantle, and crust compressing it
tremendously

12. Inner Core
* The inner core of
the Earth has
temperatures and
pressures so great
that the metals are
squeezed together
and are not able to
move.
* The inner core is a
solid.

13. Layers of the Earth

15. •Exosphere: 700 to
10,000 km (440 to
6,200 miles)
•Thermosphere: 80 to
700 km (50 to 440
miles)
•Mesosphere: 50 to 80
km (31 to 50 miles)
•Stratosphere: 12 to
50 km (7 to 31 miles)
•Troposphere: 0 to 12
km (0 to 7 miles)

18. conclusion
 Earth is made of of four layers,
the crust, mantle, and outer
core, and the inner core. Inside
and around Earth there is five
spheres, the
Geosphere(Lithosphere), the
Atomosphere, the Hydrosphere,
the Cryosphere, and the
Biosphere. These spheres all
interact to make what life what
it is here on Earth. It is the
ground we walk on, the air we
breath, the water we drink. the
cold places we live and all the
living creatures here on Earth.
