Can anyone give me a deep sea trench? and how deep is it?

Question

homework

Answer 1

Mariana Trench at a depth of 10,911 meters or 35,798 feet

Answer 2

There are a couple things to think about here. First, convergence between continental and oceanic plates only happens at the edge of continents. So a deep-sea trench that occurs in the middle of the oceans would not generally be found in this environment. Second, there is a large difference in the density of oceanic and continental crust. The continental crust is less dense, and is therefore more buoyant. So the oceanic slides below the continental crust in a convergent boundary, while the continental crust rides above the oceanic plate. As this happens, marine sediments are scraped fro the oceanic plate and stack up against the continental crust, filling in the area that could be a "trench." This is called an accretionary wedge. While this is happening, the oceanic crust begins to melt and the magma, which is less dense than solid rock, migrates toward the surface. This magma partially melts the continental crust and results in intermediate volcanoes on the surface. Volcanics also fill in the area around the accretionary wedge. So basically, you will not find a trench, but you will find intermediate-composition volcanic arcs. Check the Aleutian Islands as an example.

Answer 3

A sea trench is formed when 2 oceanic plates move towards each other. The older plate, being the heavier one, will sink beneath the younger one and subduct. the friction will pull the younger plate and it will bend at the place it meets the older one. draw a straightline from the left followed by a curve in the clockwise direction and draw another one starting from the right in the anti-clockwise direction to illustrate. in the middle, let the right curve stop above the left to show that it is the younger plate, and the trench is there, the place where your 2 lines touch.(It adds marks if you illustrate as it shows understanding) So no one can give you a sea trench unless they can converge 2 oceanic plate( which is heavier than continental plate).

Answer 4

The Marianas Trench approx. 7 miles deep

Answer 5

Yes, the Marianas trench in the south pacific past The Phillipines is the deepest trench in the world. It is some 36,000 feet down.

Answer 6

No one can give you a deep sea trench....they belong to God....however, the Marianas trench is 35,000 ft deep.

Answer 7

I thought maybe the Philippine deep is one but I'm not sure what trench it belongs to. I could guess but since it's your homework, I won't. I'm going to research too.

Answer 8

there is also a puerto rican trench 28,232 ft deep. This is the deepest part of the atlantic. It's located, as you might guess, near peurto rico

Answer 9

Kermadec Trench - just west of French Polynesia

10,047 meters deep

Answer 10

marianas trench.....deepest trench in the ocean
