Explore it!
Look at the model provided for you and answer the questions about the layers of the Earth on
your lab sheet.
Layer 1 is called the Earth’s crust. It is the
thinnest layer and made up of mostly granite
and basalt.
If you think about the outer layer of an apple,
the Earth’s crust would be compared to that.
1. Do you think this the densest layer or least
dense layer? Why?
Layer 2 is called the Earth’s mantle. It is the
thickest layer and made up of mostly magma,
which is lava within the Earth.
There are convection currents in the mantle
that cause the tectonic plates o move as the
heat flows.
2. Why do you think we know very little about
the mantle?
Layer 3 is called the Earth’s outer core. It is
made up of mostly liquid Iron and Nickel.
Layer 4 is called the Earth’s inner core. It is
made up of mostly solid Iron and Nickel.
Scientists believe the magnetic properties of
the Earth are caused by this layer of the
Earth.
It is the Earth’s densest layer. Even though
it’s as hot as the surface of the Sun, it is solid.
3. Why do you think the outer core is liquid
and the inner core is solid?
4. How do you think scientists are able to
study the center of the Earth?
Illustrate it!
Sketch the diagram on your page and label each of the layers.
Write it!
Why does the Earth have
different layers?
List the layers of the Earth
and provide a short
description of each layer
starting with the center of the
Earth.
How is density related to the
layers of the Earth?
Organize it!
Match the Earth’s layers with the correct
descriptions. Have the teacher check your
cards to ensure it is correct.They will sign
Teacher initials:
your lab sheet in the Organize It box to the
right.

movement of tectonic plates?
A. Crust
B. Mantle

D. Inner Core
Why is the inner core solid?
A. Even though it is as hot as the surface of
the Sun, it has immense pressure upon it.
B. Fe and Si
C. Ni and Si
D. Ni and C
B. Iron and Nickel are only solid
C. Because Nickel is not dense
D. Because it is made up of mostly
granite and basalt
