what landforms are formed at constructive plate boundary
Constructive or Divergent Margins. At these types of plate margins two plates are moving apart (DIVERGE) from each other in opposite directions. Convection currents moving in opposite directions (caused by the intense heat of the Earth's interior) in the mantle move two plates apart.rocesses: seismicity and vulcanicity. Associated landforms: young fold mountains, rift valleys, ocean ridges, deep sea trenches and island arcs. . Volcanoes and earthquakes mainly occur along plate boundaries where magma can escape from the earth s mantle or where stresses build up between 2 plates rubbing together.
