Crust, mantle, and core. Earth inside and out
Description
The Earth's surface is a fragile mask, and this Science Screen Report reveals the turmoil beneath it. A cutaway view of the planet depicts its layers-including its crust, hot mantle, and superheated core-and leads to an outline of plate tectonic theory. The Himalayas, the Matterhorn, and the Hawaiian Islands are analyzed as examples of tectonic and volcanic activity, while the core's relationship to Earth's magnetic field is also studied. The program includes animation that clearly demonstrates the concept of subduction.
