Section Materials


Visions of Earth, by AGI
A four-DVD set on interactions in Earth systems.

Paleomap Project, by Scotese
Navigate through this site to find animations, diagrams, resources, teaching materials, and background information. The home page describes how the site is organized and how to find what you want. In particular, the site includes maps and animations (including the breakup of Pangea and the way the continents will look in the future) of the changing positions and shapes of the continents over geologic time.

The Breakup of Pangea, by USGS
Learn more about the breakup of Pangea

Some Unanswered Questions About Plate Tectonics, by USGS
What drives the plates? This article aims to explain the connection between plate movement and convection.

Earth's Lithosphere, by National Air and Space Museum
See the lithosphere in context in terms of the shape of the Earth, plate movement, and drifting continents.

Mid-Ocean Ridges, by UC Santa Barbara
It is the longest mountain chain, the most active volcanic area and until recently, the least accessible region on the earth. New maps reveal striking details of how segments of the ridge form and evolve.

MAR: Descent to the Mid-Atlantic Ridge, by Scripps Institute of Oceanography
Follow the exhibition by a Scripps researcher and an entire scientific team, as they guided the deep submersible Alvin to probe the depths of the North Atlantic - exploring undersea mountains of the Mid-Atlantic Ridge.

Developing the Theory, by USGS
Learn about the the development of the theory of mid-ocean ridges.

Juan de Fuca Subduction - Juan de Fuca Ridge, by Cascade Range, CVO USGS
Read more about the currently active Axial Seamount which lies on the Juan de Fuca Ridge off the coast of Washington.

Birth of the Himalaya, by NOVA Online
This site accompanies the NOVA special called Everest and includes some background information on continent-contient collisions.

The Earth's Crust, by USGS
Where is the Earth's crust the thickest? Where is it the thinnest? This map shows the crustal thickness around the globe.

Visions of Earth, by AGI
82 High-definition animations showing a variety of Earth and space system processes.

On the Move - Continental Drift and Plate Tectonics, by NASA
This site includes some brief background details on how the theory of continental drift developed and how NASA monitors and tracks continental drift now. For fun, try out the mini-quiz or do the word search (which requires Java).

Plate Tectonic Animations, by USGS
See several different animations of Earth processes. Each animation comes with a short description.
