They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
What else can I help you with?
What forms when a continental plate collides with an oceanic plate?
it forms a trench
A trench forms when?
In geology a trench is formed where one tectonic plate is subducted or forced under another plate.
What were the diseases in the trench war?
trench foot when water forms fungus from being constantly submerged and the fungus eats your feet
Does Indian plate have trench forms?
Yes, the Indian plates do have trench forms. Another name for the Indian plate is the India plate. It is a tectonic plate that was originally part of ancient Gondwana.
What kind of Human impact is on the marina trench?
great life forms
What kind of plate boundary forms a deep sea trench?
A convergent plate boundary forms a deep sea trench. This occurs when two tectonic plates are pushed towards each other, causing one to subduct beneath the other, creating a trench in the ocean floor.
What is a deep valley on land the forms along a divergent boundary called?
trench
How and why does an oceanic trench form?
The earth has plates and when the earth shirfts its plates it open a trench canyon like structure. sorry if my grammer is not perfect. An oceanic trench forms when a denser plate is subducted into the Earth at a convergent plate margin. Because the denser plate (always oceanic crust) is being bent and pulled down into the mantle, a trench forms at this subduction zone.
What kind of plate boundary forms a mountain rainge and a deep ocean trench like the Andes Mountain Range and Peru-Chile trench?
oceanic-continental convergence
What is an oceanic trench?
An ocean trench is a deep canyon in the ocean floor that forms at a destructive plate margin where oceanic crust flows back into the Earth's mantle. An example would be the Mariana Trench is the deepest point in any ocean and is located in the Pacific Ocean
What plate boundary does a deep ocean trench form on?
A deep ocean trench typically forms at a subduction zone, which is a convergent plate boundary where one tectonic plate is forced beneath another into the mantle. This process results in the formation of deep trenches in the ocean floor, such as the Mariana Trench in the western Pacific Ocean.
Where would active volcanoes be found if a deep ocean trench is located adjacent to a continent?
When an overriding plate is continental, a marginal trench forms where the topographic depression seems to follow the outline of the continental margin. It is here where explosive volcanoes can be found.
