The seafloor topography indicates active plate tectonics and seafloor spreading. Key evidence from ocean bottom maps:

- Mid-ocean ridges (raised, volcanic mountain chains) — sites where new oceanic crust is created.
- Deep-sea trenches — places where oceanic plates are subducted back into the mantle.
- Fracture zones and transform faults — lateral offsets where plates slide past one another.
- Abyssal plains, seamounts, and guyots — variations produced by sedimentation and volcanic activity.
- Symmetrical magnetic striping and age patterns — youngest crust at ridges, progressively older away from ridges, confirming seafloor spreading.

Together these features show that the ocean floor is dynamic and records plate motions and interactions.
