The tectonic plates diverge (move apart) causing rift valleys (deep sea trenches) to form.

nope, ocean trenches
Deep ocean trenches form
Trenches are deep ocean features of subduction zones.
there are three ocean trenches in the Atlantic Ocean
At spreading centers.
Treches are formed when an ocean plate subducts under a continental plate.
It comes from sea mounts and ocean trenches.
Trenches
The Pacific Ocean has the deepest trenches.
An ocean trench does not become a volcanic island, however volcanic islands often form near ocean trenches.
