In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench , a trough can be a narrow basin or a geologic rift . These features often form at the rim of tectonic plates .
A trough is the opposite of a crest, so the minimum or lowest point of the wave. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line).
Some troughs look similar to oceanic trenches but possess other tectonic structures. One example is the Lesser Antilles Trough, which is the forearc basin of the Lesser Antilles subduction zone. [8] Also not a trench is the New Caledonia trough, which is an extensional sedimentary basin related to the Tonga-Kermadec subduction zone. [9]
For example, through devices fabricated from an LB trough Lee et al. [17] showed in 2006 that direct electron tunneling was the mode of transportation in alkanethiol self-assembled monolayers [18] Langmuir-Blodgett Troughs have unique advantages in nanoparticle deposition, making them capable of creating highly sophisticated coatings with ...
The Osbourn Trough, located at 25.5°S just north of the Louisville Ridge collision zone, is a 900 km (560 mi)-long extinct spreading ridge midway between two large oceanic plateaux north and south of the Tonga Trench respectively: Manihiki 1,750 km (1,090 mi) to the north and Hikurangi 1,550 km (960 mi) to the south.
Four items are required for gas collection with a pneumatic trough: [2] The trough itself, which is a large glass dish or a similar container. A gas bottle (or bulb), to hold the gas collected. A way to support the gas bottle or bulb, such as a beehive shelf or a hanger (as with Stephen Hales' design). A liquid in the trough.
Title page of the 1859 Murray edition of the Origin of Species by Charles Darwin. Lists of important publications in science cover publications in various fields of science that have introduced a major new topic, made a significant advance in knowledge or have significantly influenced the world.
The title page often shows the title of the work, the person or body responsible for its intellectual content, and the imprint, which contains the name and address of the book's publisher and its date of publication. [2] Particularly in paperback editions it may contain a shorter title than the cover or lack a descriptive subtitle.
