The gakkel ridge is formed by a divergent tectonic plate boundary between the north american plate and the eurasian plate. what would most likely be observed at this tectonic boundary? mountains created by the movement of magma into the fissure between two tectonic plates frequent earthquakes caused by the rubbing of two tectonic plates against each other destruction of the oceanic lithosphere by plate movement under the crust due to subduction chasms reaching the mantle caused by the movement of two tectonic plates away from each other
