Just under the crust is the layer called the Mantle. The Mantle is very thick, in fact, if you drove from Kansas City to Los Angeles, you would have traveled as many miles as the thickest of the earth's Mantle. Most of the Mantle is solid. Beneath the Mantle, and at the center of the earth, is the Core. The Core has two parts, the inner core and the outer core.
Scientists believe the outer core is liquid and the inner core is solid.
The core is believed to be shaped like a ball with a temperature of about 5500 degrees centigrade. Make a scale model of the earth with clay, Styrofoam, etc. Color each layer a different color, label layers, tell its thickness and approximate temperature. List the three layers of the earth. Relate the layers of the earth to the layers of your model.
