Evidence of subduction includes the presence of deep ocean trenches, volcanic arcs, and seismic activity along subduction zones. Additionally, the recycling of oceanic crust into the mantle through subduction is supported by studies of isotopic signatures and the age of rocks in different regions. Magnetic anomalies in oceanic crust also provide evidence of the movement of tectonic plates associated with subduction.

Deep ocean trenches are surficial evidence for?

plate tectonics and the process of subduction. They are formed where one tectonic plate is forced beneath another, leading to the creation of the deep trenches in the ocean floor. This process is associated with the movement of Earth's lithospheric plates.
