The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions.

Plate tectonics (from the Greek word for "one who constructs") is a theory of geology developed to explain the phenomenon of continental drift, and is currently the theory accepted by the vast majority of scientists working in this area. In the theory of plate tectonics the outermost part of...
I have used the illustrations on these pages (see menus at page top and bottom), with only minor modifications, to lead students from primary grades through graduate school in lessons about plate tectonics, volcanoes, earthquakes, and the rock cycle. When time allows, I always opt to draw th...
plate tectonics n. 1.(used with a sing. verb)A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interaction of the earth's lithospheric plates. ...
The plates under the oceans are known as the oceanic plates and the ones under continents are known as the continental plates. These plates keep moving away from or towards each other. Plate tectonics play an important role in shaping our planet. ...
One study of how heat flowed under the sea led Revelle and his colleagues to suggest that molten earth was moving under a thin layer of bedrock. That discovery was linked to the theory of plate tectonics, the idea that the surface of the Earth is composed of giant, continent-size plates ...
Plate tectonics, theory dealing with the dynamics of Earth’s outer shell that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s sur

North America - Geology, Plate Tectonics, Erosion: Continents have collided and broken apart repeatedly over geologic time. When they separate, new ocean basins develop between the diverging pieces through the process of seafloor spreading. Spreading, wh
