subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to a volcanic island arc, and about 200 km (120 mi) from a volcanic arc. hence the age of ocean floor is usually greatest in subduction zones

The ocean floor is destroyed at?
At the subduction zone of two tectonic plates.
Means the ocean floor is pulled under the continent?
This occurs in a subduction zone.
Which ocean floor feature is found near almost every subduction zone around the world?
Trench
A deep valley along the ocen floor beneath which oceanic crust slowly sinks toward mantle?
This is known as a trench in a subduction zone.
What forms when one oceanic plate is forced beneath another plate a rift valley an ocean basin an ocean ridge a subduction zone?
a subduction zone
What are the deepest part of the ocean floor?
The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone. These areas are called deep sea trenches and the Challenger Deep in the Mariana Trench in the Pacific is the deepest known point in Earth's oceans.
What feature on the ocean floor would you most likely find the oldest seafloor?
in a subduction trench, because of Harry Hess' theory of sea floor spreading. Meaning that the rock is formed new at the mid-ocean ridge, and moved out towards the coasts into a subduction zone years and years later.
What is the difference between a mid oceanic ridge and a subduction zone?
A subduction zone occurs at convergent plate margins where an oceanic plate is going underneath a continental plate or a less dense oceanic plate. A mid-ocean ridge is a divergent plate boundary on the ocean floor with a mountain range and a rift running through the center of it. Sea floor spreading also occurs at mid ocean ridges.
Location of frequent earthquakes at the subduction zone?
Ocean Trench
What happens after magma erupts along mid ocean?
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.
What forms when one oceanic plate is forced beneath another plate a. an ocean basin b. an ocean ridge c. a subduction zone d. a rift valley?
C. subduction zone
What zone appears when an ocean pate sinks beneath a continental plate?
This is called the subduction zone.
