Atlantic futures: competing supercontinent scenarios

Observations today → regional model → alternatives · future hypotheses

Explanatory illustrations of oceanic plate activity, not sections of a specific site or a settled future map. The realistic scene illustrates present-day ridge processes only.

New oceanic crust forms at ridges, while oceanic plates descend into the mantle at subduction zones. Different assumptions about changing plate boundaries lead to futures in which the Atlantic closes or continues to widen.
