On continents it is called a Rift Valley or Graben. in the ocean it is call a Mid Oceanic Ridge.
Long crack that forms as two tectonic plates move apart
The movement of tectonic plates in opposite directions is referred to as a divergent boundary.
Oceanic trenches are the gaps which form when the tectonic plates move apart. They are the very deepest parts of the ocean.
i believe its the rift valley
