trenches
submarine canyons
landslides
rewatch submit

Explanation:

Subduction occurs at convergent plate boundaries where one tectonic plate moves under another. Trenches are deep oceanic depressions formed at subduction zones as the subducting plate bends and descends. Submarine canyons are formed by erosion from turbidity currents and not related to subduction. Landslides are mass movements of rock/debris and not indicators of subduction. So Trenches are evidence of subduction location.

Trenches
