Ocean Trenches Geography revision AQA GCSE
Trenches that are deeper than about 1.5 m present safety risks arising from their steep walls and confined space. Trenches are formed through subduction, which occurs when tectonic plates collide and push one plate beneath the other. • falling into the trench. This is commonly a process of plate tectonics. Web during world war i, the battles were often fought from the mud in deep trenches built to hide from enemy fire. Unlike large excavations, a trench is generally deeper than it is wide. Web trenches are long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath. Web where do trenches form and why?

When a oceanic crust and a continental crust collied the less dense oceanic crust sinks under. Web earth science deep ocean trenches are formed when a continental plate descends underneath an oceanic plate. This is commonly a process of plate tectonics. Trenches form at a subduction zone. Web osha is focusing on reducing trenching and excavation hazards. This general purpose concrete trench drain forming system can handle flows in the 6 cfs (2700 gpm) range.
