Divergent boundaries in the middle of the ocean cause seafloor spreading and the formation of mid‑ocean ridges. That process produces several related effects:
- Creation of new oceanic crust as upwelling magma solidifies (basalt/pillow lavas).
- A mid‑ocean ridge with a central rift valley where plates pull apart.
- Shallow volcanic activity and frequent, generally low‑to‑moderate earthquakes.
- Hydrothermal (black smoker) vents and associated chemosynthetic ecosystems.
- Symmetrical magnetic striping and age patterns on either side of the ridge recording seafloor spreading.
- Gradual widening of ocean basins (e.g., Mid‑Atlantic Ridge, East Pacific Rise).
In short: oceanic divergent boundaries build new seafloor and form mid‑ocean ridges with volcanism, vents, and shallow seismicity.
