All of the following are part of sea floor spreading except

A. Sea level rising

B. plates moving closer together

C. magma fillig in gaps in oceanic plates

D. trenches forming in the bottom of the ocean floor

Answer;

A. Sea level rising

Explanation; Seafloor spreading is a geologic process in which tectonic plates split apart from each other producing new seafloor. The process of seafloor spreading results from the mantle convection which is the slow, churning motion of the mantle. It occurs at divergent plate boundaries. Seafloor spreading occurs along mid-ocean ridges, and old crust is pushed away from the oceanic ridges. Oceanic crusts move slowly from oceanic ridges and sites of seafloor spreading making them cooler, more dense and thick.

Does the Sea Level have anything to do with the Sea Floor? The Sea Level has to do with the amount of water in the sea and not how much surface area the sea floor has.
