How the Earth is Changing
This online resource is a series of web pages that describe the development of the Plate Tectonic Theory from its beginnings with Wegener's Theory of Continental Drift.
The pages follow the steps in the process of the development and refinement of a scientific theory. They also address the issue of peer review and experimentation in science.
Images and animations help explain difficult sea floor spreading concepts as well as showing the importance of this discovery in the context of providing evidence for Wegener's theory.
This resource is provided by the BBC and is designed to provide scientific information for students and teachers in accessible language using animations to help explain difficult concepts.
