1.	Why is ocean deep or trench important in the Ocean bottom?
Answer» An arc-shaped depression in the deep ocean floor is called ocean deep or trench. These are the deepest parts of the ocean floor. Ocean trenches are produced by the subduction of oceanic crust under continental crust. They resemble step sided valleys or canyons on the land. Trenches or deeps are generally parallel of the coasts facing mountains and along the islands. Great earthquakes and tsunamis generally take birth in this region.
