The document summarizes the layers that make up Earth's interior. It describes Earth's spheres as the lithosphere, hydrosphere, atmosphere, and biosphere. It then details Earth's layers, including the crust (with oceanic and continental types), mantle, outer core, and inner core. The inner core is solid and made of iron and nickel, while the upper mantle is called the asthenosphere, where convection currents occur in the plastic-like rock.

3. Earth’s Layers
 The earth has many layers, they are: Crust(Oceanic
crust and Continental crust), Asthenosphere(upper
mantle), Mantle, Outer Core, and Inner Core.
Layer Definition Translation Image
Crust The upper part of the
earth—There are two types
of crust, Oceanic and
Continental. It forms the
upper lithosphere.
• Kwout
• Croûte
• Corteza
Mantle The layer beneath the crust.
It is 2/3 of the mass of the
earth.
• Manto
• Manteau
• Manto
Outer Core Layer beneath the mantle.
It is liquid.
• nwayo ekstèn
• Noyau externe
• Núcleo externo
Inner Core The layer inside/at the
center of earth. It is solid.
• Nwayo enteryè
• Le noyau intérieur
• El núcleo interno

4. Summary
 The “Earth” is a complex planet--to the point of fascination. Many
spheres altogether support life on earth. Those spheres are the
lithosphere which means earth. The hydrosphere which is water.
The atmosphere which is the air. At last, the biosphere is made up
of all living things. That’s outside the earth. The inner part of earth
consists of the crust--the part we walk on. There are two types of
crust, Oceanic crust and continental crust. The oceanic crust is
denser than the continental crust. It is the ocean floor. The
continental crust is much thicker than the oceanic crust. It is less
dense. The upper mantle is made out of plastic-like substance. It is
called the asthenosphere. That is where convection currents
occur. The mantle is made up of molten rock(magma). The outer
core is liquid as well however it is denser than the mantle. At last,
the inner core is made out of metal-- iron and nickel. It is solid. In
conclusion, the earth’s interior is intriguing with all of those hot
layers floating on top of each other.
