What are the layers of
the Earth?
As the name suggests, the Earth's layers are concentric layers that make the Earth
function. In short, it was nature's way of organizing the Earth's mass, balancing
heat, pressure, and materials, allowing for the existence of everything we know on
the surface. Without them, the Earth would be a dead planet like the moon.
Concentric layers refer to layers
nested one inside the other.( )
Earth's crust 
It is the thinnest layer of the
Earth, functioning as a shell for
the planet, with a thickness of 5 to
80 km.
Thick. It covers the mantle and is
rich in silicon and aluminum.
 It is composed of solid rocks, such
as granite in the continental crust
and oceanic basalt.

Earth's
mantle 
It is the largest layer of the
Earth, located between the
crust and the core. Reaching a
depth of up to 2,900 km, it
represents 84% of the Earth's
total volume and is rich in
silicon, magnesium, and iron.

Outer mantle: This is the
Earth's middle layer, mostly
composed of solid rocks,
although it also behaves like a
viscous fluid due to high
pressure and temperature.

Inner mantle: The deepest portion
of the Earth's mantle, and also the
closest to the core. Formed by
solid rocks, which despite the
temperature, are prevented from
melting completely by the
extreme pressure.
Earth's
core
It is the deepest and most
mysterious layer of the earth. It
lies below the mantle. It is
composed of the outer core, a
liquid of molten iron, and the
inner core, which is solid and
even hotter than the outer
core.

Outer core: This is the only
completely liquid layer of the
Earth, located below the inner
mantle, and is composed mainly
of molten iron and nickel. Despite
being composed of molten
minerals, it is as fluid as water.

Inner core: This is the deepest
layer of the Earth, a metallic sphere
that, despite being extremely hot,
remains in a solid state. Studies
even suggest it possesses its own
rotation independent of the rest of
the planet.
What are they?:
Silicon (Si): What it is: A semimetal that is rarely found in its pure form in
nature, but rather combined with oxygen.
Magnesium (Mg): A very light and reactive mineral, essential for life; in plants, it
is the core of the chlorophyll molecule, enabling photosynthesis. 
Nickel (Ni): A corrosion- and heat-resistant transition metal used in coins and
to manufacture stainless steel.
