What Is Plate Tectonics? Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere. Developed from the 1950s through the 1970s, plate tectonics is the modern version of continental drift, a theory first proposed by scientist Alfred Wegener in 1912. Wegener didn't have an explanation for how continents could move around the planet, but researchers do now.

plate tectonics Synthesized from these findings and others in geology, oceanography, and geophysics, plate tectonics theory holds that the lithosphere, the hard outer layer of the earth, is divided into about 7 major plates and perhaps as many as 12 smaller plates, c.60 mi (100 km) thick, resting upon a lower soft layer called the asthenosphere.

Why do tectonic plates move? Tectonic plates are made up of lithospheric plates which means it consists of the crust and the part of the upper mantle above the semi viscous asthenosphere which due to temperature and pressure has peridotite melted by about 2%.

Plate Tectonics The movement of the plates is responsible for the formation of ocean basins, mountain ranges, islands, volcanoes, and earthquakes. Important concepts in the theory of plate tectonics include the following: The ocean floors are continually moving — spreading from the center, sinking at the edges, and being regenerated.

Plate Tectonics Plate Tectonics is a theory developed in the late 1960s, to explain how the outer layers of the Earth move and deform.The theory has caused a revolution in the way we think about the Earth. Since the development of the plate tectonics theory, geologists have had to reexamine almost every aspect of Geology.ectonic Theories. Tectonic theories attempt to explain why mountains, earthquakes, and volcanoes occur where they do, the ages of deformational events, and the ages and shapes of continents and ocean basins.

Plate Tectonics The theory of plate tectonics itself says that the Earth's lithosphere is made up individual plates that are broken down into over a dozen large and small pieces of solid rock.

Nystatin-Triamcinolone Cream Uses. This medication is used to treat fungal skin infections. This product contains nystatin, an anti-fungal drug that works by stopping the growth of fungus. It also contains triamcinolone, an anti-inflammatory corticosteroid that works by reducing swelling, itching, and redness. This medication treats only fungal skin infections. It will not work for other types of skin infections (e.g., infections caused by bacteria, viruses).

How Crustal Plates Move: Plate Tectonics Plate tectonics is the unifying theory of geology. This theory explains how crustal plates move around the surface of the earth, and it allows geologists to find explanations for geologic events such as earthquakes and volcanoes, as well as the many other processes that form, transform, and destroy rocks.

- plate tectonics. 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 relative to one another. Slip on faults that define the plate boundaries commonly results in earthquakes.

Plate Tectonics The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

Major Plates of the Lithosphere: Earth's Tectonic Plates The theory of plate tectonics tells us that earth's crust is broken up into plates. These plate-like sections of the earth's crust are known as tectonic plates, or lithospheric plates, and they very slowly float around on top of the hotter and more fluid asthenosphere. There are seven major tectonic plates.

- Tectonics is the theory that the earth's surface is split into  plates that float on the surface of semi-molten rock known as the  mantle layer. For instance, as the plates …are on the move, (albeit,  extremely slowly) the India Plate colliding (converging) with the  Asian Plate resulted in the formation (upthrust) of the  Himalayas.

Plate Tectonics By Amanda Briney, Contributing Writer. Plate tectonics is the scientific theory that attempts to explain the movements of the Earth's lithosphere that have formed the landscape features we see across the globe today. By definition the word plate in geologic terms means a large slab of solid rock.

What is Plate Tectonics? Report Abuse. Plate tectonics is the geological theory that describes the way in which the outer layer of the Earth's surface floats upon a semi-liquid inner layer. It's really a pretty well established description of things.he deeper mantle below the asthenosphere is more rigid again. This is, however, not because of cooler temperatures but due to high pressure. The lithosphere is broken up into what are called tectonic plates —in the case of Earth, there are seven major and many minor plates.

Earthquakes: tectonic plates There are two kinds of plates: oceanic crust (i.e. the plates under the ocean) and continental crust. Image: Tectonic plates. There are 7 large and many small moving plates. The plates have a depth of 50 miles and on average they move only a few inches a year relative to one another. Coastlines and plate boundaries do not always align. Although the upper mantle is solid rock, it slowly flows in a convection current because of heat dissipating from the core.

Plates & Boundaries The earth's continents are constantly moving due to the motions of the tectonic plates. Closely examine the map below, which shows the 15 major tectonic plates. As you can see, some of the plates contain continents and others are mostly under the ocean. The type of crust that underlies the continents is called continental crust, while the type found under the oceans is called oceanic crust.

What Is Plate Tectonics? Plate tectonics is the unifying theory of geology, said Nicholas van der Elst, a seismologist at Columbia University's Lamont-Doherty Earth Observatory in Palisades, New York. Before plate tectonics, people had to come up with explanations of the geologic features in their region that were unique to that particular region, Van der Elst said.

difference between continental drift and plate tectonics The theory of plate tectonics suggests that the plates that float on top of the asthenosphere, which hold continents, are always moving, and therefore have a tendency to bump into each other. Places where the plates meet each other are known as faults.
