Describe the Process of Subduction at a Deep Ocean Trench
Which type of zone is located at a deep-ocean trench. Trenches are formed by subduction a geophysical process in which two or more of Earths tectonic plates converge and the older denser plate is pushed beneath the lighter plate and deep into the mantle causing the seafloor and outermost crust the lithosphere to bend and form a steep V-shaped depression. Mariana Trench Facts Maps Pictures Britannica As the sinking plate moves deeper into the mantle fluids are released from the rock causing the overlying mantle to partially melt. . Convergent divergent subduction transform 2 See answers. The material of the plates is renewed by a process of being forced into the Magma usually causing a deep trench in the Ocean floor called subduction zones and by bubbling up of material from the Magma in upwelling zones. Diffusion is a very slow process. As the subducting slab moves under the less dense plate some of. The plate that is slip...
