Eric Frost (SDSU) tells the students at Kimball School in National City about the interior and exterior of the Earth.

Fig Newtons are good models of the uppermost layers of the Earth, the asthenosphere and the lithosphere. The "cookie" part is representative of the lithosphere, the rigid, outer-most layer of the Earth. The "jelly" part is representative of the asthenosphere, the layer beneath the lithosphere that flows plastically. When the Fig Newton "experiences" an earthquake, the lithosphere breaks along the fault, much like it does on the Earth.
