Scientists now have a fairly good understanding of how the plates move and how such movements relate to earthquake activity. Most movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. ... There are four types of plate boundaries:

The Story of Plate Tectonics;; The story of Plate Tectonics is a fascinating story of continents ... The Tectonic Globe; The Tectonic Globe is a unique globe that accurately describes all of the Earth's crustal tectonic features. Hand-crafted to depict mid-ocean ridges, subduction zones, island chains, and the like.

There are 3 primary types of Tectonic Plate boundaries: Divergent boundaries; Covergent boundaries; and Transform boundaries. As the giant plates move, diverging [pulling apart] or converging [coming together] along their borders, tremendous energies are unleashed resulting in tremors that transform Earth’s surface.

[edit] Other types of plate boundaries ... A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either ... List of tectonic plate interactions...

This map is configured to show the plate boundaries of the western hemisphere to advantage. It also shows the lithospheric dynamics along these boundaries: the simple picture of the early plate tectonics theory has given way to a more complex one (for a simpler outline map, ...

Plate tectonics - Wikipedia, the free encyclopedia
Plate tectonics (from the Greek τέκτων; tektōn , meaning "builder" or "mason") is a theory which describes the large scale motions of Earth's lithosphere. The theory builds on the older concepts of...

At the time, scientists thought that volcanoes only happened at plate boundaries, but nobody could explain why they were happening out in the middle of a tectonic plate. Dr. Wilson said that there are "hot spots", under the earth's crust in some places.

The Earth's outermost layers (the lithosphere) are broken into about a dozen or so plates. These thin, wide tectonic plates move around on the globe independent of one another. Most volcanoes and earthquakes are concentrated near the boundaries between plates.
