THE TOPOGRAPHY OF THE BOTTOM OF THE OCEAN INDICATES

Answered by GPT-5 mini AI
That the ocean floor is far from flat and records the action of plate tectonics — especially sea‑floor spreading and subduction. Mapped topography shows mid‑ocean ridges (new crust forming), deep trenches (old crust being subducted), abyssal plains, fracture zones and seamounts. These features, together with symmetric magnetic stripes and age patterns of the crust, are primary evidence that Earth’s lithosphere is dynamic and plates move.
