1. Inside the Ball
What is under your feet?

2. The earth's interior is neither all solid nor is it all molten (liquid).
There are layers with a different density, thickness and composition.

5. The Earth’s crust is separated into plates
Some plates are quite small while others are quite large.
They all float and move on top of the molten asthenosphere. (Analogy: like a boat in water)
When they push together and when they pull apart they create "tectonic forces". (Analogy: like a car crash)

7. The deepest part of the earth (1512 miles deep) is a solid layer that contains both iron and nickel.
This layer is the Earth’s magnet…which keeps us from flying out of our orbit
The Inner Core

8. Outside of the inner core lays the outer core (1419 miles deep).
This is much like the inner core with the exception that it is a liquid that contains sulphur and oxygen
The Outer Core

9. Occupying 1789 miles of the earth is the magma (iron and magnesium).
It is mostly solid except the outer Km which is extremely hot and goopy; very plastic-like. 
This outermost liquid layer of the mantle is referred to as the asthenosphere.
This is magma (lava
under the earth’s crust

10. Mohorovicic Discontinuity
Boundary between the mantle (asthenosphere) and the Lithosphere.
Very thin layer
Like oil in an engine
Mohorovicic Discontinuity

11. This is the top layer of the earth, which is basically hardened mantle (magma). It contains two segments, the oceanic and continental crusts.
Note: this is the same crust, it just depends how thick it is to determine if it is part of the Oceanic or Continental Crust. For instance, if you drained all of the water from earth, then there would be one, giant Continental Crust. Likewise, if you flooded everything, you'd have one, giant Oceanic Crust.
