An easy-to-understand explanation of what plate tectonics is. Contains information about the inner parts of the Earth, the difference between the three types of plates, and numerous maps and illustrations.

This sequence is an introduction to plate tectonics using evidence from topographical maps, earthquake location and depth, and volcano location using the Seismic Explorer model to investigate patterns of earthquake data and to infer the...

Observe the relationship among volcanoes, earthquakes and lithospheric plates by collecting data and creating maps. This activity was created to be used with the NOVA program, "Deadly Shadow of Vesuvius" but the video is not necessary...

The theory of plate tectonics revolutionized geology in the 1960's. In this project you can explore the connection between plate tectonics and earthquakes by mapping historical seismic data.

The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data.

An in-depth look at the structure and composition of Earth's mantle, with lots of visuals. Covers lithosphere, Mohorovicic discontinuity, asthenosphere, transition zone, lower mantle, the d double-prime region, mantle convection, mantle...

This site is primarily set up as an outline and is loaded with graphs, maps, and images. It covers a variety of earthquake-related topics, such as what causes earthquakes, fault lines and structures, seismology, a historical look at...

A rich collection of highly engaging learning modules on topics related to the natural environment. Covers four main areas - plate tectonics, forms and processes, weather and climate, and rainforest and desert. Within each of these,...
