What Is Plate Tectonics? From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past. 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.

- Full Definition of PLATE TECTONICS. 1. : a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates.

What is Theory Of Plate tectonics? Submit. · just now. Report Abuse. Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen plates that move around across the earth's surface relative to each other, like slabs of ice on a lake.est Answer: the theory that the earth is made of massive plates beneath the surface that move every so often which is how we get earthquakes. and this also goes back to Pangea if you know what that is.

PLATE TECTONICS Tectonism is the deformation of the lithosphere, and the term tectonics refers to the study of this deformation, including its causes and effects, most notably mountain building. This deformation is the result of the release and redistribution of energy from Earth's core.

Plate Tectonics: Theory & Definition Plate Boundaries and Motions. A plate boundary is what we call the edge of a plate, where it is in contact with an adjacent plate. Along these boundaries, plates are in constant motion, either away from, towards or past each other.

Plate tectonics Definition: What is plate tectonics. The concept that describes and explains how the major features of the Earth form and/or deform. The essential processes of plate tectonics are 1)seafloor spreading and 2) subduction. These two processes operate on basic units called plates. Key surface features such as mountain ranges form in particular tectonic settings when these processes act on plates directly or indirectly. Plates exist as a consequence of the specific conditions of temperature and pressure, and materials found on Earth. Plates move around, and change in size and number over geologic time.

What is the theory of plate tectonics? exists and is an alternate of . Plate tectonics is the science and study of the causes of, and relative motions of, Earth's lithospheric plates. The lithospheric plates are composed of the rocky crust and outermost rocky layer of the mantle which are fused together.

- But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theor … y aren't really two separate things. However plates are pieces of the Earth's crust which are moving.

plate tectonics plate tectonics. In geology, a theory that the Earth's lithosphere (crust and upper mantle) is divided into a number of large, plate-like sections that move as distinct masses.

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: A Unified Theory for Change of the Earth's Surface This new theory of large-scale change on the earth is known as plate tectonics. Plate tectonics is the theory that the surface of the earth is broken into larger pieces of crust called plates that ride along on a softer layer of the earth, known as the asthenosphere, which is the upper part of the mantle.

- Plate tectonics is the scientific theory that Earth's outer layer is made up of plates or blocks that move, which accounts for why mountain and volcanoes form and earthquakes happen. The surface of Europa -- one of Jupiter's four largest moons and slightly smaller than Earth's moon -- is riddled with cracks and ridges.

What Is the Definition of Tectonic Plates ? Quick Answer. According to the U.S. Geological Survey website, tectonic plates are massive, irregular-shaped slabs of solid rock, composed of oceanic and continental lithosphere. The continental crust is made up of lightweight minerals like feldspar and quartz, while the oceanic crust is made of heavier and denser basaltic rocks. Keep Learning.

- 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.

Continental Drift: Theory & Definition Plate tectonics is now the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing, according to Encyclopedia Britannica.
