What chain of events will most likely occur to Iceland in the future?
A.
The rift will widen between the two plates, and new volcanoes will be pushed up from the sea floor to create a volcanic arc running through Iceland.
B.
As the rift increases in size, a new crust will be created on either side of it, which will eventually fill with soil and become a low-lying valley running through Iceland. C.
The rift will widen, forming a subduction zone and resulting in an ocean trench and the formation of an island arc that separates the two halves of Iceland.
D.
The rift will widen between the plates; new crust will form on either side of the rift, water from the ocean will rush in, and eventually, Iceland will split apart.
