Theory suggesting that the Earth's surface is composed of a number of oceanic and continental plates. Driven by convection currents in the mantle, these plates have the ability to slowly move acr [..]

The unifying geologic theory developed to explain observations that interactions of the brittle plates of the lithosphere with each other and with the softer underlying asthenosphere result in large-s [..]

A theory of global tectonics according to which the lithosphere is divided into mobile plates. The entire lithosphere is in motion, not simply those segments composed of continental material. compare continental drift

movement and interaction of the Earth's plates.

Plate Tectonics is the theory supported by a wide range of evidence that considers the earth's crust and upper mantle to be composed of several large, thin, relatively rigid plates that move rela [..]

the movements of continental plates over the mantle whose currents pull them around the Earth's surface. As far back as 1912, Alfred Wegener noted that the continents fit together like puzzle pieces into some lost whole (see Pangaea, a name he coined). He was ignored, but in 1929, Arthur Holmes decided that thermal convection currents in the m [..]

The theory that the earth's crust is broken into about fragments (plates,) which move in relation to one another, shifting continents, forming new ocean crust, and causing volcanic eruptions.

the idea that the Earth's lithosphere can be divided into a number of plates that move and interact with each other along their boundaries.

(n) - the theory that Earth's surface is covered by a dozen plates that converge and diverge

The mechanism by which the plates that make up the surface of the Earth interact with one another, including the formation and subduction of oceanic crust.

Large crustal plates moving on the Earth's surface and resulting in changes in the Earth's surface.

The theory that the Earth?s lithosphere is made up of rigid plates that are in relative motion with respect to each other.

Geologic theory that the bending (folding) and breaking (faulting) of the solid surface of the earth results from the slow movement of large sections (plates) of that surface.

the movement of the Earth’s lithospheric plates due to convection in the mantle. Precise

The process by which the Earth’s plates continuously move over top of the mantle (Lesson 26)

Synthesis of geological and geophysical observations in which the Earths lithosphere is thought to be divided into seven large rigid plates, and several smaller ones, that are moving relative to each [..]

The theory that the earth's surface is divided into a number of rigid plates that are either converging, diverging, or slipping past one another; these motions generate volcanism and earthquakes along the plate boundaries.

The theory that the crust and part of the mantle are divided into plates that interact with each other causing seismic and tectonic activity.

is the name for the theory that provided the evidence necessary to support Wegener’s hypothesis.

The theory that the Earth’s outer shell is made up of about a dozen lithospheric plates that move about and interact at their boundaries.

A theory that explains the movement and deformation of parts of the outer Earth. It involves the movement of rigid lithospheric slabs, called plates, over a less rigid layer ( the asthenosphere).

The theory that the Earth's outer shell is made up of about a dozen lithospheric plates that move about and interact at their boundaries. more details...

Concept that the Earth's crust is composed of rigid plates that move over a less rigid interior.

movement of the crustal plates comprising Earth's surface, with continents "riding" them polyp

a theory that large "plates" of the Earth's colder, upper crustal rocks are capable of moving slowly (like rafts) on top of deeper, hotter, and more fluid rocks in the mantle. Geologists have identified seven large plates and 11 or more smaller ones on the Earth's surface.

The process of planetary surface plate formation, movement, interaction, and destruction. The consequence of this process is that many regions of the planet are situated near interacting--and slowly m [..]

Theory describing the possibility on how earth’s crust is broken into plates, suggesting that those plates move thru and across earth’s surface.

refers to the folding and faulting of rock and flow of molten lava involving lithospheric plates in the earth's crust and upper mantle.

pleyt tek-ton-iks Earth's solid crust is broken up into about a dozen semi-rigid plates, boundaries of which are zones of tectonic activity.

 The theory that states that the Earth's crust is split into a number of plates that slowly move around, causing earthquakes and volcanoes.
