Question

How are ocean treanches formed??

Answer 1

Trenches are formed by subduction, a geophysical process in which two or more of Earth's 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

Answer 2

trenches are formed by subduction a geophysical process in which two or more of earth's tectonic plates coverage and the older denser plate and deep into the mantle causing the seafloor and outermost crust to bend and form a steep v_shaped dispersion
