This article describes the theory of plate tectonics and its relation to earthquakes and seismic zones. Materials include an overview of plate tectonics, a description of Earth's crustal plates and their motions, and descriptions of the four types of seismic zones. Full description.

This site provides an introduction to plate tectonics using color maps and text descriptions. Links are also provided for maps of recent earthquakes in the western United States, the world and in the Los Angeles area. Full description.

This frequently-asked-questions feature provides answers about earthquakes, faults, plate tectonics, and earth structure. Maps and diagrams are provided with some answers, and links to additional information and to related topics are included. Full description.

This on-line project is part of the Center for Improved Engineering and Science Education (CIESE) program. As they complete this series of lessons, students will use real-time data to solve a problem, study the correlation between earthquakes and tectonic plates, and determine whether or not there is a relationship between volcanoes and plate boundaries. Musical Plates has four Core Activities that ... Full description.

According to theory of plate tectonics, Earth is an active planet -- its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates. This interactive feature shows the relationship between earthquakes and volcanoes and the boundaries of tectonic plates. By clicking ... Full description.

This site offers the online version of a book published by the United States Geological Survey (USGS). It is intended to provide a brief introduction to the concept of plate tectonics, highlighting some of the people and discoveries that advanced the development of the theory. It is the companion volume to the map, 'This Dynamic Planet', which shows the locations of major volcanic belts, fault systems, ... Full description.

This is a brief overview of the Theory of Plate Tectonics. According to the theory, the Earth's surface layer, or lithosphere, consists of seven large and 18 smaller plates that move and interact in various ways. Along their boundaries, they converge, diverge, and slip past one another, creating the Earth's seismic and volcanic activities. These plates lie atop a layer of partly molten rock called ... Full description.

This site explains the basics of plate tectonics. It was devised for the eighth grade students at Beal High School in the United Kingdom but is suitable for any English speaking middle school student. The site covers sea-floor spreading, subduction, convergent boundaries, collision boundaries, and transform boundaries. The site uses animated illustrations to explain how plate motion causes earthquakes, ... Full description.

This map shows Earth's tectonic features, volcanoes, earthquakes, and impact craters. Smaller inset maps are included to depict the North and South Poles. The back of the map provides additional information, highlighting examples of fundamental processes; and providing text, timelines, references, and other resources to enhance understanding. The main and polar maps feature online interactive versions. ... Full description.

This portal provides access to a large variety of educational materials, puzzles, and games on the topics of plate tectonics and continental drift. Links are presented here on earthquakes, volcanoes, mountain building, folding and faulting, hot spots, and a selection of "Top 10" most extreme mountains, sea trenches, and earthquakes.
