 Plate Tectonics - MSN Encarta
Plate Tectonics, theory of global tectonics (geological structural deformations) that has served as a master key, in modern geology, for understanding the structure, history, and dynamics of the Earth’s lithosphere, which includes the crust.
Although the plate tectonics revolution in geological thought occurred only recently (in the 1960s and 1970s), the roots of the theory were established by earlier observation and deduction.
Where an oceanic tectonic plate is subducted beneath continental crust, the magma produced by subductive melting erupts from volcanoes situated among long, linear mountain chains, such as the Cordillera, up to 100 km inland from the zone of subduction.

Plate tectonics is a vital part of the global cycle that maintains the carbon balance between atmosphere, hydrosphere and lithosphere.
The plate boundaries (see the diagram) are characterised by different types of tectonic activity, depending on whether new crust is being formed or old crust destroyed.
Where plates move past each other, transform faults develop, associated with which are some of the world's major earthquake zones, e.g., the San Andreas fault in California, where the Pacific plate is moving eastwards against the north-north westwards moving North American plate at a rate of ~ 1 cm per year.

 Earth's Continental Plates - ZoomSchool.com
At the boundaries of the plates, various deformations occur as the plates interact; they separate from one another (seafloor spreading), collide (forming mountain ranges), slip past one another (subduction zones, in which plates undergo destruction and remelting), and slip laterally.
Seafloor spreading is the movement of two oceanic plates away from each other (at a divergent plate boundary), which results in the formation of new oceanic crust (from magma that comes from within the Earth's mantle) along a a mid-ocean ridge.

Iceland is splitting along the spreading center between the North American and Eurasian Plates, as North America moves westward relative to Eurasia.
As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed.
The descending plate also provides a source of stress as the two plates interact, leading to frequent moderate to strong earthquakes.

 Continental Drift and Tectonic Plates
These plates (and the more numerous minor plates) move in relation to one another at one of three types of plate boundaries: convergent (two plates push against one another), divergent (two plates move away from each other), and transform (two plates slide past one another).
Plate tectonic theory arose out of two separate geological observations: continental drift, noticed in the early 20th century, and seafloor spreading, noticed in the 1960s.
The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which "float" on the fluid-like asthenosphere.

The Mid-Atlantic Ridge, the boundary between the North American and Eurasian Plates, is a spreading margin.
Because the movement of plates correlates directly with the prevalence of geologic hazards, it is generally riskier to live near plate boundaries than on stable areas of the continents.

Tectonic plates are comprised of two types of lithosphere: continental and oceanic lithospheres; for example, the African Plate includes the continent and parts of the floor of the Atlantic and Indian Oceans.
Where a dense oceanic plate collides with a less-dense continental plate, the oceanic plate is typically thrust underneath, forming a subduction zone.
Tectonic plates across the globe are constantly shifting - though slowly, usually by a few centimetres a year - with the magma beneath the crust.

There are several entirely oceanic plates (Nazca, Cocos), but no entirely continental plates (with the possible exception of the Arabian peninsula; it depends on the criteria one uses to define individual plates and how much ocean is required to be considered "ocean").
The fact that continents are included as part of plates made of both continent and ocean suggests that the continents do not move independently of the oceans as Wegener envisioned, but rather that continent and ocean move together as part of a single plate.

Where an oceanic plate collides with a continental plate, the oceanic plate tips down and slides beneath the continental plate forming a deep ocean trench (long, narrow, deep basin.) An example of this type of movement, called subduction, occurs at the boundary between the oceanic Nazca Plate and the continental South American Plate.
Plate tectonics, the branch of science that deals with the process by which rigid plates are moved across hot molten material, has helped to explain much in global-scale geology including the formation of mountains, and the distribution of earthquakes and volcanoes.

The theory that describes this is known as plate tectonics.
There was probably a very much larger amount of carbon dioxide in the Earth's atmosphere when the Earth was first formed, but it has since been almost all incorporated into carbonate rocks and to a lesser extent dissolved into the oceans and consumed by living plants.
Plate tectonics and biological processes now maintain a continual flow of carbon dioxide from the atmosphere to these various "sinks" and back again.

These are zones where two plates move away from each other, allowing magma from the mantle to rise up and solidify as new crust.
Magmas that form island arcs are produced by the partial melting of the descending plate and/or theoverlying oceanic lithosphere.
The zone between two plates sliding horizontally past one another is called a transform-fault boundary, or simply a transform boundary.
