The volcanic landforms at divergent ocean plate boundaries are oceanic ridges.

Divergent boundaries, convergent boundaries, and transform boundaries are all cracks in the Earth's crust. They are located where the Earth's plates border one another.
Hi when to plates pul apart under the ocean its called tectonic plate drift or contenetial drift.This allows countries to moves centimetres evvey year in any direction the plate travels.sometimes the plates rub and can cause earthquakes ,volcanos or tsunamis.
Trenches occur at convergent boundaries when one tectonic plate which is more dense, is pushed beneath another tectonic plate that is less dense. This process is called subduction. Usually where divergent boundaries in the earth's crust are. When faults move apart, they create trenches.<-- no divergent boundaries in the ocean create mountain ridges not trenches http://upload.wikimedia.org/wikipedia/en/a/a4/SubZone.jpg
mountain chains at divergent boundaries are called
Divergent boundaries - two plates Pull away from each other. Convergent boundaries - when two plates collide forming trenches or causing earthquakes. Tranform boundaries - two plates slide past each other
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
Older material
If the divergent boundary is located between two ocean plates, the lava that erupts will likely be called mafic. This lava is relatively low in silica but high in magnesium and iron.
Spreading centers.
Diverging tectonic plates.
Divergent Boundaries
They are called constructive boundaries. New crust is constructed as the plates move apart and magma erupts.

Hot spot volcanoes are not associated with a plate boundaries. Hot spots can drive volcanic activity all by themselves.
They are called divergent plate boundaries.
