Transcript The Layer`s Of The Earth!

The Layers of the
Earth!
Earth Layers
• The Earth is divided into four main
layers.
*Inner Core
*Outer Core
*Mantle
*Crust
The Crust
* Like the skin of an applevery thin compared to
the other three layers.
*The crust makes up 1% of
the Earth. It is 20 miles
deep.
* The crust of the Earth is
broken into many pieces
called plates.
The Mantle
• The mantle is the
layer below the
crust.
• The mantle is the
largest layer of the
Earth = 4,000 miles
deep
• The mantle is
divided into two
regions: the upper
and lower sections.
Outer Core
* The core of the
Earth is like a ball of
very hot metals.
* The outer core is
liquid.
* The outer core is
made up of iron and
is very dense.
Inner Core
* The inner core of
the Earth has
temperatures and
pressures so great
that the metals are
squeezed together
and are not able to
move.
* The inner core is a
solid, 800 miles
deep.
The Earth Bowl
• First, everyone will receive their materials:
1. A plastic cup
2. A napkin
3. An Oreo
The rest of the materials will be passed out by me as
we go along!
DO NOT TOUCH ANY OF THE MATERIALS AFTER
YOU HAVE RECEIVED THEM. WAIT UNTIL I
EXPLAIN WHAT TO DO.
The Steps to Making the
Layers!
1. First you will need to place the Oreo in the
plastic cup. This will form the “core” of the
Earth because it is solid and dense.
2. Next, we will make the outer core, this will be
made of lemon pudding. I will be coming
around with the pudding. BE PATIENT!
3. Now, we will be making the mantle.
Because this is more solid than the
outer core but not completely solid, we
will be using Jell-o. Be patient as I
come around with the Jell-o.
4. Now to top it all off we will be making
the crust! I will be coming around with
Rice Krispies and graham cracker
crumbs.
You have now made the
Layers of the Earth!
*The Crust (Rice Krispies)
*The Mantle (orange Jell-o)
* The Outer Core
(lemon pudding)
* The Inner Core (Oreo)

3. The mantle is the largest layer of the Earth. True or
False
4. Is the Outer Core a liquid or a solid?
5. The Earth Bowl graham cracker or Rice Krispies layer
represents the Earth’s ________, which is 20 ______

Answers!
1. Crust, Mantle, Outer Core, Inner Core
2.Thin
3.True
4. Liquid
5. Crust; miles
6. Hot
Remember
In the classroom the Earth Bowl took only
a few hours to make; in actuality the
earth took 5 billion years to form.
