2. which of the following correctly describes seafloor spreading? a. new oceanic crust is formed in the middle of tectonic plates and then spreads outward in bands. b. new oceanic crust is formed at deep-sea trenches, pushed away from the trench, and destroyed at midocean ridges. c. new oceanic crust is formed at midocean ridges, pushed away from the ridge, and destroyed at deep-sea trenches. d. new oceanic crust is formed at seamounts and spreads outward in all directions.

The answer is option C.

Explanation:

New maritime hull is shaped at mid-sea edges, pushed far from the edge, and wrecked at remote ocean trenches.  Ocean bottom spreading occurs in the "mid-sea ridges".  truth be told, the significance of Seafloor spreading is that it is a procedure that happens at mid-sea edges, where new maritime hull is created through volcanic action and afterward gradually moves separated from the edge.

answer; i believe the correct answer is ; large pieces of pangaea drifted in different directions over millions of years;
