  7) has more information and a drill for the
  students to watch drill to the center of the
  Earth.
• On page 9 is a eating activity to help the
  students remember all of the layers of the Earth.

The Layers of the Earth

• Inner Core
• Outer Core
• Mantle
• Crust

Crust
Lithoshpere

• The Earth's outermost surface is called the
  crust. The crust is typically about 25 miles
  thick beneath continents, and about 6.5 miles
  thick beneath oceans. The crust is relatively
  light and brittle. Most earthquakes occur within
  the crust. The crust in this image is much
  smaller in the real earth!

Is made up of the Crust and the Moho.
Moho
is the dividing line between the Crust and the
Mantle.

Mantle
Athenoshpere
is the outer layer of the mantle.

• The region just below the crust and extending all
  the way down to the Earth's core is called the
  mantle. The mantle is relatively flexible so it
  flows instead of fracturing.

6
Core

• Beneath the mantle is the Earth's core. The
  Earth's core consists of a fluid outer core and a
  solid inner core. Because the outer core contains
  iron, when it flows it generates a magnetic
  field. This is the source of the Earth's magnetic
  field.

Have the students use 9 oz. clear cups to create
the Earth. Put the students in groups. Have the
students do a write about their activity.
