Lesson 1
Layers of the Earth

Objective:
Identify the layers of the Earth (crust, mantle, core). - S11/12ES-Ia-e-7
Differentiate the layers of the Earth. - S11/12ES-Ia-e-8

The earth is a complex system consisting of four subsystems. These
subsystems are geosphere, hydrosphere, atmosphere, and biosphere. All of
these subsystems interact with one another in order to carry out the different
processes on earth.

Geosphere is the solid part of the earth. It includes the interior structure
of the earth, the land forms, the rocks and minerals and all the processes on
the surface of the earth. The continents and the ocean floor are part of the
geosphere. It means that the geosphere covers the solid part of the earth,
from the surface which is the crust to the deepest part which is the core.

The earth’s structure is composed maily of the three main layers with
different characteristics. These layers of the earth are crust, mantle and
core.

Activity 1: Match Me

Direction: Match the layers of the earth to their deffinition. Draw line to
connect the boxes.

CRUST It is the center of the earth that is ma-
de up of iron and nickel.

MANTLE The outermost and the thinnest layer
CORE of the earth. It consist of loose rocks
MOHO and soil.
ASTHENOSPHERE
It is found above the upper mantle
that is still part of the crust. It is the
transitional boundary that divides the
mantle and the crust

It lies on the upper part of the mantle
and directly below the crust. It is com-
posed of soild flowing rock.

The thickest layer of the earth that
contains molten rock called mag-
ma. It holds almost 84% of the earth
volume.

CLOSURE

Geosphere is the solid part of the earth that includes the different
continents and the ocean floors, from its surface down to the deepest part
which is the core. The internal structure of the earth composes mainly of the
crust, mantle and the core.

The different layers vary in their characteristics like density,
temperature, mineral composition and thickness.

Crust is about 5 to 7 km thick. The oceanic crust is thinner than the
continental crust. The crust is composed mainly of oxygen, silicon, iron,
aluminum, sodium, calcium, magnesium and potassium. Just above the
upper mantle and below the crust id the mohorovicic discontinuity (Moho).
This layer is recognized as the transitional boundary between crust and
mantle.

Mantle is the thickest layer of the earth. It is made up of silicate rocks.
It hold about 84% of the earths volume. Recent studies reveal that there is a
layer between crust and mantle which is called the asthenosphere that
directly lies on the upper portion of the mantle and below the crust.

Core is subdivided into outer core and the inner core. They are
mainly made up of iron and nickel. The iron that is found in the outer core in
in liquid state while the inner core is in solid form.
