Definition: plate tectonics: A geological model in which the Earth's lithosphere (crust and uppermost mantle) is divided into a number of more-or-less rigid segments which move in relation to one another.

The front plate of a chevron pair for use in X-ray astronomy usually has channels perpendicular to its front surface, since the X-rays emerging from a grazing incidence telescope do so along the surface of a cone.

Plate tectonics involves the formation, lateral movement, interaction, and destruction of the lithospheric plates.

When two plates move towards each other, several features can form. Often, one of the plates is forced to go down into the hot asthenosphere at a subduction zone.

Although the majority of practical photography has been done using film for almost a century, glass plates were used in astronomy up until the last decade.

Plate tectonics is the now-established theory that of the (plates) float on the surface and change both position and size over time.

plate tectonics - (n.)
the theory that the Earth's continental and oceanic crust and outermost portion of the mantle is fractured into large plates that move relative to each other.

plateau -- Any comparatively flat area of great extent or elevation.
plume -- A buoyant mass of hot, partially molten mantle material that rises to the base of the lithosphere.

Plate tectonics: Theory formulated in the late 1960s that states the Earth's crust and upper mantle (a layer called the lithosphere) is broken into moving pieces called plates.

plate tectonics -- the hypothesis that the crust of the Earth (or some other planet) is divided into large regions (plates) that move very slowly over the planet's surface.

The plateau phase in Type II-P supernovae is due to a change in the opacity of the exterior layer. The shock wave ionizes the hydrogen in the outer envelope, which greatly increases the opacity.

Some plates snapped in two during the one hour exposure in the cold dome with a large BOOM-- badly startling me. Slipher seemed resigned to accepting a few broken plates, but I could not.

New: Plate tectonics of Earth description has been greatly expanded along with the various ways that plate tectonics helps to keep Earth habitable. New images added of Jupiter's four major moons. New information about Mercury's core.

PLATE TECTONICS
Plate tectonics is the now-established theory that chunks of the Earth's crust (plates) float on the surface and change both position and size over time.

photographic magnitude (symbol mpg) Stellar magnitudes measured from a photographic plate exposed without filters. Photographic plates are more sensitive to short wavelengths than the human eye.

The photographic plates for the Atlas and the care of their preparation for publication represented a high point in the photography of galaxies.

The front of the tube contains a glass lens known as the corrector plate. Light enters through the corrector plate where it strikes the primary mirror in the back of the tube.

It is not known when the original continental cores formed or how long ago modern plate-tectonic processes began to operate.

Analysis of the satellite data indicates that Mars appears to lack active plate tectonics at present; there is no evidence of recent lateral motion of the surface.

Two major centers of past volcanic activity have been identified: the Elysium Plateau and the Tharsis bulge. Some of the solar system's largest volcanoes occur in Tharsis.

The sky, the abode of the stars, is described as a "raḳia'" (a plate); that is, a rigid, broad, solid plate possessing a certain thickness.

If you have ever looked at a hot plate heating up on a stove, you have an idea of why this might be true. At first, you don't see any light coming out of the hot plate, but you feel its heat.

With modern photographic plates, which have been developed specially for astronomy, and filters to isolate different regions of the spectrum astronomers can use large field telescopes to obtain plates covering several square degrees of the sky.

This high plateau region in the interior of the peninsula is just up the road from Olympia. Now called Pholois, this is where the Centaur stories of antiquity originated.

A spiral galaxy is similar to a huge spinning plate. If you look at a spinning plate from its edge, the left part of the plate will be moving in one direction and the right in the opposite direction.

Earth's seven continents sit on large tectonic plates that float atop the mantle. Eons ago, the continents were joined together into a single land mass scientists have coined Pangaea.

plasma consists of a gas heated to sufficiently high temperatures that the atoms ionize.

The crust is made of many vast 'plates' that are constantly moving very slowly. Where two plates touch is a 'fault', which is responsible for creating new islands - via the release of molten lava into the water - when located just beneath the ocean.

It took them years to analyze the data because rather than relying on automatic detectors to spot new particles, they used the older method of recording particle tracks on plates of photographic emulsion and then painstakingly examining each plate ...
