Question

Quizplus · Accepted Answer

Deep sea trenches are sites where the oceanic lithosphere is consumed into the mantle in subduction zones. This process is an important aspect of plate tectonics, as it helps to shape and renew the Earth's crust. The study of deep sea trenches therefore provides valuable insights into the dynamics of plate movement and the processes that drive it.
