How are ocean depths related to plate tectonic processes? Be sure to include divergent boundaries, convergent boundaries and abyssal plains in your answer.
According to the “plate-tectonics” theory, the Earth’s surface is broken into a number of shifting slabs or plates, which average about 50 miles in width. These plates move in relation to one another above a hotter, deeper, more mobile zone at average rates as great as a few inches per year. “plate tectonics“ appear as powerful new hypotheses that geologists used to interpret the features and movements of the Earth’s surface layer.
