Which of the following is NOT evidence that the continents had moved over time?

The correct choice highlights that subduction zones themselves are not evidence of continental movement but rather a result of that movement. Subduction zones occur where one tectonic plate moves under another and is forced into the mantle, playing a significant role in the overall dynamics of plate tectonics.

In contrast, earthquake activity, mid-ocean ridges, and plate tectonics provide direct evidence for the movement of continents. Earthquake activity tends to occur along plate boundaries where stress from moving plates is released. Mid-ocean ridges represent the creation of new oceanic crust as tectonic plates pull apart, further indicating that continents and oceanic areas are in motion. The theory of plate tectonics itself outlines the mechanisms by which the continents move, providing foundational support for the idea of continental drift over geological time.

Thus, while subduction zones are essential to understanding tectonic processes, they do not directly demonstrate the historical movement of continents, which is the underlying reason for choosing this option.
