Maybe you have even started, in your

you…

Earth’s four layers:
Crust
Mantle
Outer core
Inner core
These four layers are:
the crust,
the mantle,
the outer core,
and the inner core.
QUESTION A
By using advanced techniques, scientists have determined the layers beneath the
surface of our Earth, which are:
A. The crust, the middle, and the bottom.
B. The core, the inner core, the outer core, the mantle, and the lower mantle.
C. The inner core, the outer core, the mantle, and the crust.
D. The crust, the mantle, and the core.

The crust is the top and outermost layer—it is
all that you can see and what you live on.
You may have noticed that the crust can look
very different from place to place.

This now brings us to the innermost layers:
the outer core and the inner core.
The outer core is liquid and is mainly made of
iron and nickel.

The ancient Greeks determined the size of
the Earth.
Around the turn of the 20th century,
scientists determined the layers of the
Earth.
These 4 main layers are the crust, the
mantle, the outer core, and the inner core.

This layered configuration can be
compared to a hard-boiled egg.
<Image>
The crust is the outermost layer and is
very thin compared to the others. Like an
egg’s shell, the Earth’s crust is brittle.

Below the crust is the mantle: a dense, hot
layer, which can be likened to the white of
a boiled egg.

At the center of the Earth is the core. The
core is similar to the yolk of the egg. The
core is divided into the outer core, a thick
metallic liquid; and the inner core, which is
solid.

The Earth is layered, like an onion.
The thinnest layer, the crust, is very
similar to the skin of an onion.
The crust makes up approximately one
percent of the Earth’s volume.

of the Earth.

Place a double ended arrow showing
approximately 3/4 of the interior (from the
outer edge toward the center), and label it

Beneath the crust is the mantle, which
makes up the largest layer of the Earth.
Several of the onion’s layers would
comprise the mantle.
The mantle is approximately 84% of the
Earth’s volume.

The very center of the Earth is the doublelayered core.

All known life exists on the solid outer
layer of the Earth called the crust. The
crust is what creates our landforms, such
as mountains and valleys.

The crust is one of the four layers of the
Earth. It is the top layer that we all see and
live on.
<Image>
If you could keep digging through the
crust, you would encounter the mantle,
which is a flexible, magma-like substance.

The crust is made up of tectonic plates.
The tectonic plates form our continents
and the world as we know it today.

So what does that have to do with making
mountains and oceans?
Tectonic plates move over long periods of
time and can form mountains.

This is like the tectonic plates when they
push against each other and form
mountains.
<Image
Oceans rest on thinner tectonic plates and
do not “float” as high above the mantle.
Water runs off the higher plates
(continental plates) to the lower plates
(oceanic plates) forming oceans.
