Question

Ocean trenches form over millions or billions of years. Which statement accurately describes how ocean trenches form?(1 point)

Answer 1

Ocean trenches form through the process of subduction, where one tectonic plate is forced underneath another plate at a convergent boundary. This process happens gradually over millions or billions of years, as the subducting plate is slowly pushed deeper into the mantle. As the plate sinks, it creates a trench-like depression on the ocean floor, known as an ocean trench.
