Final answer:
Deep trenches tend to be found near the edges of continents because the oceanic plate is subducting under the continental plate.
Step-by-step explanation:
The correct piece of evidence that supports the theory of plate tectonics is Deep trenches tend to be found near the edges of continents because the oceanic plate is subducting under the continental plate. Deep trenches, such as the Mariana Trench, are located at convergent plate boundaries where one tectonic plate is forced underneath another in a process called subduction. This evidence demonstrates the movement and interaction of tectonic plates.
