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.

What is a Plate? Plates are on average 125km thick, reaching maximum thickness below mountain ranges. Oceanic plates (50-100km) are thinner than the continental plates (up to 200km) and even thinner at the ocean ridges where the temperatures are higher.

General Astronomy/Print version The motion of the earth's plates is called plate tectonics. Tectonics is derived from a Greek word tekton which means carpenter or builder. Tectonics is the study of the movement and deformation of the lithosphere.

plating A thin, flat sheet of metal or other material, especially one used as an electrode in a storage battery or capacitor. 2. In plate tectonics, one of the sections of the Earth's lithosphere (crust and upper mantle) that is in constant motion along with other sections. See more at tectonic boundary.

How to Dig Post Holes 1 If you have time, start the holes one day, fill them with water and come back to remove the much softened soil the next.  Post hole diggers have a maximum effective depth of about 3/4 of their handle length, so a five foot pair will dig about 3 1/2 half deep.

Plate Tectonics A tectonic plate itself is defined as a rigid segment of the Earth's lithosphere that moves separately from those surrounding it. There are three main driving forces for the movement of the Earth's tectonic plates.

- Janet17. The theory of plate tectonics states that Earth's outermost layer, the lithosphere, is broken into 7 large, rigid pieces called plates. They are floating on the Earth's mantle, a really thick layer of hot flowing rock.

- No they are not the same thing.    Plate Tectonics is the study of mechanisms and the results of  large-scale movement of the earth's crust.    Tectonic Plates … are large sections of the earth's crust that float  on top of semi-molten rocks of the upper mantle.

Plate (dishware) Probably used as a charger to place other tableware on. A plate is a broad, concave, but mainly flat vessel on which food can be served. A plate can also be used for ceremonial or decorative purposes. Most plates are circular, but they may be any shape, or made of any water-resistant material. Generally plates are raised round the edges, either by a curving up, or a wider lip or raised portion. Vessels with no lip, especially if they have a more rounded profile, are likely to be considered as bowls or dishes, as are very large vessels with a plate shape. Plates are dishware, and tableware. Plates in wood, pottery and metal go back into antiquity in many cultures.

Ask GeoMan... This is an easy one. The earth's crust is broken into sections, called plates. There are two (2) basic types: oceanic plates which are composed of basalt, and continental plates, which are mostly granite. The continental plates are in motion, and literally bounce around on the surface like giant air hockey pucks.

Continental Drift: Theory & Definition Plate tectonics is the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1950s and 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing.

Plate Tectonics Tectonics is a part of the Greek root for to build and together the terms define how the Earth's surface is built up of moving plates. 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. These fragmented plates ride next to each other on top of the Earth's more fluid lower mantle to create different types of plate boundaries that have shaped the Earth's landscape over millions of years.

Plate tectonics Plate tectonics. Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός pertaining to building) is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, over the last hundreds of millions of years.
