Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which combatants are well-protected from the enemy's small arms ...
A gas main being laid in a trench. A trench is a type of excavation or depression in the ground that is generally deeper than it is wide (as opposed to a swale or a bar ditch), and narrow compared with its length (as opposed to a simple hole or pit). [1] In geology, trenches result from erosion by rivers or by geological movement of tectonic ...
In case of default, different tranches may have conflicting goals, which can lead to expensive and time-consuming lawsuits, called tranche warfare (punning on trench warfare). [4] Further, these goals may not be aligned with those of the structure as a whole or of any borrower—in formal language, no agent is acting as a fiduciary. For example ...
A trench marks the position at which the flexed, subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to and about 200 km (120 mi) from a volcanic arc. Much of the fluid trapped in sediments of the subducting slab returns to the surface at the oceanic trench, producing mud volcanoes and cold seeps.
A ditch is a small to moderate trench created to channel water. A ditch can be used for drainage , to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation .
Site of the Battle of the Trench, Medina. The Battle of the Trench (Arabic: غزوة الخندق, romanized: Ghazwat al-Khandaq), also known as the Battle of Khandaq (Arabic: معركة الخندق, romanized: Ma’rakah al-Khandaq) and the Battle of the Confederates (Arabic: غزوة الاحزاب, romanized: Ghazwat al-Ahzab), was part of the conflict between the Muslims and the Quraysh.
A bump from the trench in the oceanward side of the system is present (Barbados in the Lesser Antilles is an example). The fore-arc basin forms between the fore-arc ridge and the island arc; it is a region of undisturbed flat-bedded sedimentation.
Slab pull is a geophysical mechanism whereby the cooling and subsequent densifying of a subducting tectonic plate produces a downward force along the rest of the plate. In 1975 Forsyth and Uyeda used the inverse theory method to show that, of the many forces likely to be driving plate motion, slab pull was the strongest. [1]
