Structure of the Earth
http://scign.jpl.nasa.gov/learn/plate1.htm


This site explains that seismologic studies of the Earth have revealed that it has several distinct layers. Each of these layers has its own properties and this information has helped to give credence to plate tectonic theory. There is an interactive diagram of the Earth that shows and describes the layers. In addition, each layer is described and diagramed in detail. There are also active links to a Glossary of Terms for unfamiliar words in the text.
